摘要：
Two-dimensional transverse magnetic (TM) wave scattering from a cavity-backed slit in a ground plane is analyzed by Harrington and Mautz's generalized network formulation. The admittance matrix of the cavity of arbitrary shape and medium is obtained by the finite element method. The computed admittance matrix, added to the radiation admittance matrix of the equivalent magnetic current on a ground plane, is used to solve for the equivalent magnetic current on the slit. Numerical results for coated staggered cavities are included.
