Abstract :
In this paper, we analyze the impedance strip diffraction problem for H-polarized plane wave incidence by means of an analytical-numerical approach. Applying the boundary condition to an integral representation of the scattered field, the problem is formulated as simultaneous integral equations satisfied by the electric and magnetic current density functions. The integral equations are reduced to two infinite systems of linear algebraic equations (SLAE) using a method similar to that employed for the E-polarized case, which are solved numerically with high accuracy via a truncation procedure. Physical quantities are then expressed in terms of the solution of the SLAE. Illustrative numerical examples on the monostatic and bistatic RCS are presented, and the far field scattering characteristics are discussed
