A fundamental approach: E-polarized electromagnetic wave diffraction by two dimensional arbitrary-shaped objects with impedance boundary condition

Abstract In the present study, a new methodology in computational electromagnetics is developed for two-dimensional arbitrarily-shaped objects with impedance boundary conditions. The proposed approach investigates E-polarized electromagnetic diffraction by object Leontovich condition. scattered electric and magnetic fields are expressed as convolution integral of corresponding Green’s function current induced on obstacle surface. After obtaining equations applying condition, solved case method auxiliary sources (MAS) which well-known electrodynamics. results compared first, different methods such moments (MoM), orthogonal polynomials (OP), second, conditions Dirichlet, Neumann, fractional Some also obtained shape scatterers at some values surface impedance.
