User's materials can be organized in a single or multiple libraries.
Yes. In addition to conductivity, you may define a surface roughness of the conductor.
No. Simulating at discrete frequency point may take a long computational time. For faster simulation time, you should use HFWorks's Fast Frequency Sweep (FFS) feature.
No need for screen captures, cutting and pasting, or switching between applications. Both EMS and HFWorks come standard with report generator and viewers. Report generation automatically captures all figures, input and output data into an html and/or Word documents. The reports can be viewed, edited, or printed directly from the SolidWorks application interface. The generated report can readily be shared with others.
To protect your work from accidental changes, we recommend that use the Study Locking feature in both EMS and HFWorks. A locked study may be viewed but cannot be edited or changed. Of course, you can always unlock the study if you need to make changes.
No. You simply clone the original study, i.e. make a copy of it, and make the necessary changes in the cloned study. A cloned study inherits all features of the original study, i.e. study properties, materials, boundary conditions, excitations, mesh, etc.

There are two major sub-domains in electromagnetics: low-frequency and high-frequency domains. Both domains are governed by Maxwell's equations.
The low-frequency domain includes the major part of the electromagnetic devices such as bushing, insulators, circuit breakers, power generators, transformers, electric motors, capacitors, magnetic levitation devices, synchronous machines, DC machines, permanent magnet motors, actuators, solenoids, etc.
Strictly speaking, any application in which displacement currents are negligible can be classified as low-frequency. The absence of the displacement currents de-couples the electric and magnetic fields and the situation becomes static.
The high-frequency domain includes the study of electromagnetic waves and propagation of energy through matter. It may be some times difficult to distinguish between high-frequency and low frequency. Nevertheless, we can generally say that electromagnetic fields in which the displacement currents cannot be neglected belong to the high-frequency domain. The displacement currents couple the electric and magnetic fields to each other and the situation becomes fully dynamic. Examples of devices that use high-frequency include antennas, waveguides, transmission lines, filters, couplers, dielectric resonators, etc.
Electrostatic is the branch of science that deals with the phenomena arising from stationary and/or slow-moving electric charges. Electrostatic approximation rests on the assumption that the electric field is irrotational, i.e. the curl of the electric field is null. From Faraday's law, this assumption implies the absence or near-absence of time-varying magnetic fields, i.e. the derivative of the magnetic field with respect to time is also null. In other words, electrostatics does not require the absence of magnetic fields or electric currents. Rather, if magnetic fields or electric currents do exist, they must not change with time, or in the worst-case, they must change with time only very slowly. In some problems, both electrostatics and magnetostatics may be required for accurate predictions, but the coupling between the two can still be ignored.
The EMS/Electrostatic module is primarily used for computing electric potential and electric field due to charges and voltages in insulators and conductors.It has many practical applications, including:
• High Voltage Components
• Insulating Systems
• EMC Compatibility
• Bus Bars
• MEMS
• Shielding
• Cables
• Switchgear
• Transformers
• Electronic tubes
• Capacitors
• Transmission Lines
Electric Conduction is, in essence, based on the electrostatic approximation. Unlike the Electrostatic analysis which deals with insulators and electric conductors, the Electric Conduction deals with only conducting media which can sustain a current flow.
The EMS/ Electric Conduction module is primarily used for computing current flow in conductors due voltage differences. . It has many practical applications, including:
• Resistors

Magnetostatics is the study of static magnetic fields. In electrostatics, the charges are stationary, whereas here, the currents are steady or dc(direct current). As it turns out magnetostatics is a good approximation even when the currents are not static as long as the currents do not alternate rapidly. Furthermore, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.
In EMS/ Magnetostatic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Ampère's law, i.e. the curl of the magnetic field is equal to the static electric current density, are invoked to compute the magnetic field and its related quantities due to electric currents and permanent magnets. It has many practical applications, including:
• Motors and generators
• Linear and rotational actuators
• Relays
• MEMS
• Magnetic recording heads
• Magnetic levitation
• Solenoids
• Loud speakers
• Electromagnetic Brakes and Clutches
• Magnetic bearings
• MRI
• Sensors
AC, or alternating current, Magnetic, is the study of magnetic fields due to alternating, or time harmonic, currents. Similar to Magnetostatic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.
In EMS/AC Magnetic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Faraday's law,, i.e. the induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit, are invoked to compute the magnetic field and its related quantities due to alternating electric currents and voltages. It has many practical applications, including:
• AC Motors and generators
• Sensors
• Coils and transformers
• Inverters
• Converters
• Bus bars
• Inductors
• NDT and NDE
• Inductive heating and hardening
• Eddy current meters

Transient Magnetic, is the study of magnetic fields due to time varying currents, typically caused by surges in currents. Similar to Magnetostatic and AC Magnetic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.
In EMS/ Transient Magnetic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Faraday's law,, i.e. the induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit, are invoked to compute the magnetic field and its related quantities due to permanent magnets and time varying electric currents and voltages. It has many practical applications, including:
• Switch on/off modes and failures in power electronic devices
• Saturation in steel cores
• NDT and NDE
• Inductive heating and hardening
• Induction machines
• Levitators
• Motors and generators

Scattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behaviours of linear electrical networks when undergoing various steady state stimuli by electrical signals. Although applicable at any frequency, S-parameters are mostly used for networks operating at radio frequency and microwave frequencies where signal power and energy considerations are more easily quantified than currents and voltages. S-parameters change with the frequency are readily represented in matrix form and obey the rules of matrix algebra.
The HFWorks/S-parameters analysis belongs to the high frequency electromagnetic, or the full wave, regime, i.e. Maxwell's displacement current that couples the electric and magnetic fields is significant and thus taken into consideration. The vector wave equation, i.e. combination of the full Maxwell's equations, is solved using vector finite element to obtain the S-parameters and the electric/magnetic fields and related design parameters. It has many practical applications, including:
• Connectors
• Filters
• Couplers
• Attenuators
• Terminators
• Baluns
• Integrated Circuit
• Waveguides
• Power dividers
• Multiplexers
• Power combiners
• Transitions
Resonance is the tendency of a system to oscillate with larger amplitude at some frequencies than at others. These are known as the system's resonant frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores energy. When loss is small, the resonant frequency is approximately equal to a natural frequency of the system, which is a frequency of unforced vibrations. Some systems have multiple, distinct, resonant frequencies. Resonance phenomena occur with all types of waves: there is mechanical resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance, electron spin resonance and resonance of quantum wave functions.
In HFWorks/Resonance analysis, we are concerned only with electromagnetic resonance. The vector wave equation, i.e. combination of the full Maxwell's equations, is solved using vector finite element to obtain the natural resonant frequencies and their corresponding electric/magnetic field distributions. It has many practical applications, including:
• Dielectric resonators
• Filters
• Resonators
• Microwave Circuits
• Microwave Ovens
• Food and industrial heating
• Wood drying and processing
• Resonator antennas
• High Q structures
• Linear accelerators
An antenna is a transducer that transmits or receives electromagnetic waves. In other words, antennas convert electromagnetic radiation into electric current, or vice versa. Antennas generally deal in the transmission and reception of radio waves, and are a necessary part of all radio equipment. Antennas are used in systems such as radio and television broadcasting, point-to-point radio communication, wireless LAN, cell phones, radar, and spacecraft communication.
Using HFWorks/Antenna analysis, antennas of all types and shapes can readily be simulated. The vector wave equation is solved using vector finite element to obtain the near/far antenna fields and all related antenna parameters such as gain, directivity, efficiency, pattern, etc. All sort of antennas can be studied, including:

Analysis/Synthesis pages allows you to go from physical to electrical parameters or vice versa quickly and easily. Get a complete set of transmission line parameters including primary transmission liner parameters. ATLASS also gives you full control over the synthesis process.
The Sweep page enables you to get real insight into the behaviour of your guiding structure as any of its parameters, i.e., dimensions, frequency or material properties, are swept of a range of values. See these results in graphical format and understand how your design might be sensitive to tolerances and process variations.
The Seamless Finite Element Analysis, for any of ATLASS's over 70 guiding structures, you may carry out fullwave 2D filed analysis for multiple modes automatically and very quickly. Gain insight into mode distributions and transmission line properties without ever worrying about drawing, meshing, boundary conditions, etc.
The SmithChart & Tools pages give you a handy SmithChart calculations, conversions, wave calculations and commonly used physical constants are all standard parts of ATLASS.
Both. However, most of the structures in ATLASS are commonly used in high frequency applications.

Gdansk University of TechnologyNon-destructive testing (NDT) team at the Solid State Physics Department of the Faculty of Applied Physics and Mathematics cooperates on the broad scale with industry representatives in developing methodology and apparatus for magnetic NDT.
Currently we are optimizing Pipeline Inspection Gauge (PIG) with Magnetic Flux Leakage (MFL) system to evaluate technical condition of pipelines. Such system consists of magnetizing yoke and magnetic field sensors. Working PIG can reach velocity of even 10 m/s due to liquid media pressure. Our job is to model effect of velocity on eddy currents generation and hence distortion of MFL signal.
We have heard about the EMWorks software as a result of searching for Finite Element Modelling (FEM) software which would be adequate for our purposes. After the review of various offers we stated that EMS has all features we need. The great advantage of this package is that it is based on SolidWorks. Thanks to this design of even very complex models becomes child's play. My first magnetostatic model in EMS was created in just a few minuts! I highly recommend EMWorks software for all those who need friendly interface as well as professional FEM software.

University of British ColumbiaOur design will revolve around the analysis of a new electron catcher (Faraday cup) and design an Electron Catcher for target station EMS from EMWorks has been a valuable tool for integrating electromagnetic component design into our SolidWorks environment.
EMS has allowed us to simplify the development stages for RF and high power AC componentry by reducing the number of experiments required during prototyping. The intuitive user interface combined with the simple transition between the design environment and finite element suite ensure that any required changes to a design can be completed, implemented, and brought back into the EMS environment for further simulation in a very short timeline.
Thank you for your valuable tool and help

Dartmouth CollegeI used EMWorks for an undergraduate biomedical engineering project. I am thankful that EMWorks is very well integrated with SolidWorks, which makes constructing 3D geometries straight-forward. The step-by-step tutorial of EMWorks also helped me in learning the software. Many other multiphysics software applications don't have easy-to-use tutorials. Overall, EMWorks has been helpful software for my project.

University of Siegen GermanyI got used to EMS very fast. I just needed two days to get a first result. Especially the simplicity to apply boundary conditions or to refine the mesh at certain surfaces or solids is great! And also the options to plot the results are very nice and intuitive. In the end the results of the simulation matched very well with the experimental values.
Paul M. Kurowski, Assistant Professor
Western UniversityI used EMS to teach the third year undergraduate course "Finite Element Methods for Mechatronic Systems Engineering". Students were already familiar with and SOLIDWORKS Simulation and Electromagnetics; they had no troubles learning EMS and working on meaningful assignment problems all within one lab. The use of EMS definitely added value to the course and enhanced students' learning experience.

Oxford Brookes UniversityEMS is quite useful program for finding electric and magnetic fields in unorthodoxly shaped assemblies. It has been especially helpful for me when I was trying to design circuits with high voltage and current applications, which are potentially lethal for students. EMS comes with a set of tutorials that guide users through the model setup and demonstrate a large variety of applications. Overall, a very professional electromagnetic simulation software.
John Lomba, a student
University of Massachusetts LowellMy First impression of HFWorks right out of the gate was, “ Brilliant”. Having HFWorks integrated directly into SolidWorks saves me so much time when it comes to building and testing coaxial RF connectors. I was very impressed with one click I was able to obtain TDR results of my RF model which really gives me everything I am looking for, especially when other software like HFSS makes it such a pain to get similar results.
Michelle Wei, Massachusetts General Hospital
Harvard Medical SchoolThe EMS magnetostatics module has been amazing for designing permanent magnet configurations to optimize magnetic field shape. The interface with SolidWorks is really intuitive and I was able to start using it quickly. Even better, the customer service and tech support have been wonderful! I highly recommend this software.
