Homogenization of corrugated interfaces in electromagnetics

Kristensson, Gerhard LU (2005) In Progress in Electromagnetics Research-Pier PIER 55. p.1-31
Abstract
A surface with periodic corrugations of sufficiently small

periodicity is shown to be electromagnetically equivalent to an

inhomogeneous transition region (slab). Explicit expressions for

the inhomogeneous transition region are found for one-dimensional

corrugations and for two-dimensional corrugations a local elliptic

problem has to be solved in order to find the equivalent electromagnetic

properties. The homogenized surface can be characterized by its

surface impedance dyadic or its reflection dyadic. A few numerical

examples illustrate the theory.
