Abstract
ABSTRACT In this paper the rigorous solution of transverse electric (TE) and transverse magnetic (TM) plane wave scattering from a Perfect Electromagnetic Conductor (PEMC) strip located at the planar interface of two half spaces (dielectric and chiral medium) is presented by applying Kobayashi Potential (KP) method. Initially, the reflected field in dielectric and also transmitted Beltrami fields in chiral medium are divided into left and right handed fields. Then, contribution of the strip in terms of Bessel eigenfunctions is added as a perturbation to the dielectric and the chiral medium fields. Then, by applying the boundary conditions, utilizing the Weber–Schafheitlin (WS) discontinuous integrals and the Jacobi's polynomials, governing equations of infinite summations with unknown coefficients are derived. The infinite summations are effectively truncated with high numerical accuracy. Next, by solving the matrix equations, the unknown coefficients are calculated. Besides validating the method with the convergence analysis, an asymptotically comparative analysis with other investigations is also provided. Finally, the study of Echo Width (EW) for interesting parameters are depicted. The method is extremely accurate and is applicable to both narrow and wide strips. Also the presented formulations are validated by some methods (KP, physical optic and method of moment).
