摘要
An accurate numerical solution for the electromagnetic scattering from an infinite strip grating is presented, where the strips are loaded with a symmetrical pair of dielectric slabs. The direction of propagation and the polarization of the incident plane wave are arbitrary. The boundary value problem is reduced to a solution of singular integral equations, which are discretized by an application of the moment method. Numerical computations are performed mainly for the purpose of designing polarization diplexers. Dependence of diplexing characteristics on grating parameters is examined in detail. Appearance of cross-polarized field at skew incidence is referred.
