Abstract
Electromagnetic scattering of metallic column covered by double-negative (DNG) metamaterials is simulated with auxiliary differential equation method in Finite-Difference Time-Domain method. Lossy Drude polarization and magnetization models are used to simulate DNG media. Numerical result shows that though the backward scattering of metallic column covered by DNG media decrease, the forward scattering increase. The effects to the backward scattering caused by the variation of DNG media's depth, plasma frequency, damping frequency and incident wave frequency are discussed.
