Abstract

In this study, electromagnetic scattering from inhomogeneous impedance periodic surfaces have been solved by means of transformation of problem into equivalent problem, that is, scattering from plane represented by transformed boundary condition. Transformed boundary condition is determined by functions of the shape and impedance of the surface. Then, transformed equivalent problem is solved by means of series expansion method using Floquet modes. This transformation makes the problem simple formulation and computational effectively without involving calculation of slowly converging periodic Green's function. Results and computational times obtained by transform method and those obtained by Method of Moment (MoM) technique are compared. Good agreements are observed in results. It is also observed that transform method needs much less computational time than MoM method.© 2008 Wiley Periodicals, Inc.
