About HFWorks

HFWorks is an antenna and electromagnetic simulation software for RF, Microwave, mm-wave, and high speed digital circuits. HFWorks solves electromagnetic radiation, electromagnetic waves, electromagnetic propagation, electromagnetic resonance, electromagnetic interference (EMI), electromagnetic compatibility (EMC), and signal integrity (SI) problems for RF/MW frequencies and beyond.  It uses state-of-the-art finite element solvers and meshing technologies to compute fields as well as antennas and circuit parameters. It can simulate single antenna elements as well as multiple array antenna configurations. HFWorks can also be used for time domain computations such as TDR and Eye Diagram. It can predict power handling capabilities of 3D structures and localize potential field breakdown areas. It also provides the capability to simulate RF microwave heating as a function of applied power.

Main Features and capabilities

Versatile High Frequency and High-Speed Tool: Whether your design involves antennas, RF and Microwave components, signal integrity, power integrity, EMC/EMI, chip-packaging, PCB, connectors, cables, RF MEMS, or filters and   whether you use planar circuit technologies, standard waveguides or dielectric guides, HFWorks covers your high frequency field simulation design needs for RF frequencies and much beyond.  Whether you are interested in frequency response, resonance behavior, electromagnetic interference, matching networks, filtering characteristics, attenuation, electromagnetic radiation, electromagnetic waves, electromagnetic propagation, electromagnetic compatibility issues, you will find this 3D field EM simulation tool accurate, fast, versatile, and easy-to-use.  

It is an antenna software as much as it is a filter, a resonator, an EMC, an EMI, a passive component, a signal integrity, and power integrity software.  HFWorks is equipped with multiple solvers: Antennas, S-parameters, Time Domain and Resonance.  

Solidworks embedded: HFWorks is seamlessly integrated in Solidworks and Gold Certified by SOLIDWORKS® Corporation.  Its seamless CAD integration enables you to analyze the most complex high frequency and high speed electrical and electronics devices and circuits in record time because you do not need to create a special model for the electromagnetic simulation.  Don’t “reinvent the wheel", simply grab a CAD model from the drafting department or colleague and start your 3D EM simulation instantly.  Since it is built on top of the most popular CAD software packages, you can import designs in a wide range of popular CAD and geometry kernel formats including Parasolid, ACIS, IGES, STEP, STL, CATIA, ProE, DXF, DWG, etc,.

Grabcad, 3dcontencentral, traceparts: In recent years a burgeoning number of free 3D CAD models -millions- have become available in CAD depositories such as,, and  Consequently, you can simply grab a CAD model from the depositories, make necessary changes, and start your high frequency electromagnetic analysis instantly.  

User friendly interface and embedded learning materials: Intuitive and easy to use graphical user interface. It allows user to construct and simulate complex 3D models in record time. The demo viewer feature in the software gives you access to extensive training material for fast learning and adoption of HFWorks.

Parametric simulation: HFWorks enables numerous analyses to obtain the best design for your application. Any CAD dimension or a simulation variable can be set as a parameter to study the effect of its changes on your design. This serves as a first step to optimize your designs.

Time Domain Solution: HFWorks comes with a Time Domain Analysis type that helps designers to allocate discontinuities in connectors and electrical path. It is a very important issue for RF connectors and cables manufacturers.

Integrated Electro-Thermal Analysis: HFWorks comes with an integrated Electro-Thermal Analysis. It offers you a coherent environment where you can simultaneously study the electrical and thermal behavior of your high frequency design right on the same model with one single finite element mesh. Hence, in addition to the plethora of electrical and electronic design parameters, you can also obtain the temperature, temperature gradient, and heat flux of your high frequency design due to conductor and dielectric losses.  

Power handling: There are two important aspects related to power handling capabilities of passive RF & Microwave structures and HFWorks covers them both. Dielectric breakdown is a key limiter of power handling as it can lead to catastrophic failure. HFWorks produces safety factor maps that indicate where breakdown has occurred in the model or where it is most likely to occur for a given level or excitation power or stored energy. Runaway thermal breakdown can also occur if any part of the design is subject to excessive heat due to RF power losses. HFWorks’ coupled thermal solver is seamlessly integrated with the electromagnetic solver to allow users to explore their model’s thermal behavior as a function of applied power. These features save users costly and time consuming experimental setups that are often required to establish power rating and handling capabilities of their products.

HFWorks Add-ins: HFWorks comes with two add-ins:

  • Mini Atlass: is an analysis and synthesis program for computing electrical and physical parameters of different types of transmission lines. It communicates directly with SolidWorks to create the structure.

  • ECAD Importer:  is an ECAD-MCAD translator that links between HFWorks and other Electronic design software such as KeySight ADS and Cadence Allegro.

    At SCP Science, we produce industrial microwave heating systems. We have been using HFWorks since 2012 to design  antennas for microwave heating, RF traps, couplers for our reflectometers, and coaxial-waveguide transitions. Most of these designs were fabricated and the measurement results closely match the simulation results obtained from HFWorks. Being fully embedded inside SolidWorks, HFWorks has given us a distinct advantage. We did not need to export the assemblies to create drawings needed for the machine shop.

    We have been using the Antenna and the S-Parameter features of the software. We are particularly pleased with the speed of the fast sweep. We also found the technical support provided by EMWorks prompt and professional.

    “… For our company, the SolidWorks files are the primary source of design information and I needed a high-frequency analysis tool that can seamlessly work with the mechanical software without having to generate another set of files for simulation totally disconnected from the official design information. HFWorks provides a true integration with the mechanical design without compromising on the available features. I used HFWorks to find unwanted resonances in our hybrid packages but also to find complex transfer functions from PCB pads to input pins to internal ceramic network. I can visualize problematic areas using the powerful graphical tools provided. Post-processing TDR function also helps me match design with lab measurements.

    I strongly recommend HFWorks for analysing complex 3D structures when simplistic 2D/2.5D models won’t get you where you wanted”...

    I 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.

    My 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.
