Feko is well suited to the simulation and optimisation of waveguide components. Due to the typically metallic structures, they can be analysed accurately and efficiently with the method of moments (MoM) and finite element method (FEM) solvers.

Applications include waveguide filters, couplers, circulators, diplexers and multiplexers. Waveguides are also used to feed certain antennas.

Key features:
  • Efficient solvers suited to simulating typical waveguide geometries.
  • S-parameter analysis, import / export of Touchstone files and general network blocks for circuit representation.
  • Parametric model creation using canonical shapes through GUI or scripting, and extensive CAD import support.
