Features and capabilities

The S-parameters module calculates the scattering parameters for RF and Microwave passive components. It also represents the S-parameters on a Smith Chart. This module can help study many RF & microwave devices and address numerous dispersion and matching effects. Below is just a partial list:

  • Obtain the vector frequency response of arbitrary 3D circuit/structure.
  • Design around a resonance.
  • Distinguish between common and differential modes.
  • Achieve a good matching over a frequency range.
  • Study the frequency response of a structure.
  • Account for both dielectric and conductor losses.
  • Study the fidelity of a high frequency structure.
  • Achieve or avoid a mode conversion.
  • Study the signal integrity of a structure.
  • Examine both propagating and evanescent modes.
  • Examine both fundamental and higher order modes.
  • Optimize pole-zero placement of a filter.
  • Study the effect of material and dimension on the circuit and field parameters.
