Abstract
A new mode matching method is presented for the electromagnetic scattering from large cavity-backed apertures. The new method is based on the expansion of the field inside the cavity by the standard modes, and a periodic extension of the field on the cavity aperture to the whole ground plane. The computation cost is low by solving only the coefficients of the modes. Numerical examples are presented to show the efficiency of the approach.
