Scattering by an infinite array of multiple parallel strips

The transverse electric (TE) and transverse magnetic (TM) electromagnetic scattering solutions for an infinite array of multiple parallel strips are considered. The solution is found using the perturbational form of the modified residue calculus technique (MRCT). In particular, the solution is found from the canonical problem of an infinite periodic array of semi-infinite parallel plates. Numerical results are presented and discussed. In addition, numerical results are given for a polarizer application.
