Abstract

This paper presents a dispersive Finite-Difference Time-Domain (FDTD) modelling of electromagnetic cloaking devices. The radial dependent permittivity and permeability of the cloaking shell are mapped to Drude dispersion model and taken into account in dispersive FDTD modelling. Numerical simulations of both the plane-wave and point-source incidence cases demonstrate that under ideal conditions, objects placed inside the shell are "invisible" to external electromagnetic fields.
