DIFFRACTION BY DIELECTRIC-LOADED MULTIPLE SLITS IN A CONDUCTING PLANE: TM CASE

A new and exact series solution for the scattering and coupling problems by dielectric-loaded multiple slits in a perfectly conducting screen is presented. The case of normal incidence and TM polarization is considered. The scattered and transmitted elds are represented in terms of an in nite series of radial modes. By applying the appropriate boundary conditions, the coe cients of scattered and transmitted elds are obtained and some numerical results are given.
