Diffraction by a Lossy Double-Negative Metamaterial Layer: a Uniform Asymptotic Solution

By Gianluca Gennarelli and Giovanni Riccio
Progress In Electromagnetics Research Letters, Vol. 13, 173-180, 2010


A uniform asymptotic solution is presented for evaluating the field diffracted by the edge of a lossy double-negative metamaterial layer illuminated by a plane wave at skew incidence. It is given in terms of the Geometrical Optics response of the structure and the transition function of the Uniform Geometrical Theory of Diffraction, and results easy to handle. Its accuracy is well-assessed by numerical tests and comparisons with a commercial solver based on the Finite Element Method.
