Resonant scattering from a slit coupled cylindrically eccentric impedance cavity: The case of H-polarized plane wave incidence

The resonant scattering characteristics of a slit coupled cylindrically ecc entric impedance cavity are examined using direct integration equation tech nique, and the incident wave is assumed to be a H-polarized plane wave. Suc h a slit coupled eccentric impedance cavity is assumed to be infinite in le ngth and of infinitely thin wall surrounded by several impedance screens. B y using the Galerkin's method combined with translational addition theorem for cylindrical wave functions, a system of linear equations of infinite or der for determining the induced current distributions are derived in an ana lytical form. Therefore, numerical results are presented to show the effect s of cavity geometrical and impedance parameters on the resonant scattering characteristics of some typical structures in the far zone.
