When circuit trace lengths become comparable to the wavelength, full wave 3D EM analysis must be used to simulate such circuits. Typical geometries and phenomena to model, include:

  • Traces on and in multi-layer substrates
  • Via connections between traces on different layers
  • Results over a wide band
  • Coupling between ports (parasitic and intended)
  • Near fields and radiated far fields

FEKO features applicable to simulation of such problems include:

  • Multi-layer planar dielectric MoM for the analysis of substrates
  • Adaptive frequency sampling for efficient calculation of wide band results
  • Import/export of S-parameters from/to Touchstone (*.SnP files)
  • Distributed memory solution for fast calculation of large problems with many structures embedded in multi-layer substrate
