Abstract

The increasing interest in electromagnetic effects in double-negative (DNG) materials requires a formulation capable of a full analysis of wave propagation in such materials. We develop a novel technique for discretization of the Drude medium model and adopt multi-domain pseudospectral time-domain (PSTD) algorithm and well-posed PML formulation to analysis the plane wave scattering properties of a single circular cylinder and a periodic array of the circular cylinders fabricated from the Drude medium. The simulation results show accuracy of the proposed constitutive equation-discretization scheme.
