摘要：

Electromagnetic wave scattering from a Perfect Electric Conductor (PEC) strip located at the interface of dielectric-Topological Insulator (TI) medium by using Kobayashi Potential (KP) method for Transverse Magnetic (TM) and Transverse Electric (TE) polarization is represented and discussed. Initially, diffracted fields equations are expressed by integral equations terms that contain unknown weighting functions. By choosing proper expression for weighting functions and exploiting Weber-Schafheitlin integrals properties, some boundary conditions satisfied automatically. The procedure leads to matrix equations which their size are chosen sufficiently, ergo the solution converges with rapid pace. Formulation, validation and convergence analysis of the proposed approach is represented and for the result, effect of structure's parameters on Radar cross section (RCS) of the configuration is elucidated and portrayed.
