Abstract: The electromagnetic characteristics of transmission and scattering properties of a slit in a conducting plate filled with anisotropic media for TM polarization are dealed with. A general frequency domain method-the Generalized Network Formulation is simply introduced. To the best of our knowledge, this problem has not been dealt with in publications. The boundary element method(BEM) and Generalized Network Formulation are implemented to solve this problem and some examples are presented. The computed results are in agreement with the one obtained in isotropic case.This illustrates the feasibility of presented scheme. Two examples of the RCS and transmission coefficients for a slit filled with anisotropic media are also presented.

Key words: anisotropic medium, boundary integral method, slit, electromagnetic scattering
