Transmission and Reflection Coefficients
Calculate the properties of frequency selective surfaces (FSS) in a multilayer scattering scenario by using transmission and reflection coefficients for plane waves. Use in conjunction with periodic boundary conditions (PBC), multilayer planar Green's functions or infinite planes for a more efficient solution.
Note: Only a single plane wave is supported (no additional sources are allowed) when
requesting transmission / reflection coefficients.
The model must either contain:
- planar multilayer substrate without any other geometry / mesh in the model
- a 2D periodic boundary condition (PBC).
The transmission coefficient is defined as:
