Bandpass FSS
Calculate the transmission coefficient of a second order, electrically thin bandpass FSS (frequency selective surface) structure. The structure is modelled with a periodic boundary condition and is excited with an incident plane wave.
Model the structure using the following two solvers:
- The method of moments (MoM) solution with the surface equivalence principle (SEP).
- The hybrid finite element method and method of moments (FEM/MoM) method.
