Abstract :
Based on dispersive FDTD method, a computation model of a cloak on a rough surface is established in this paper. In this model, the cloak is modeled as a metal cylinder covered by cloak material with equivalent permeability and permittivity. Monte Carlo method is used to generate different rough surfaces. Numerical results for the scattering from the rough surface with and without cloak are given. The Comparison of these numerical results shows the influence of the cloak on the scattering of rough surface can not be ignored.
