Abstract：In this paper, the Asymptotic Waveform Evaluation (AWE) technique is applied to study electromagnetic scattering analysis of Double-NeGative (DNG) medium. The PMCHWT equation of the DNG is deduced based on its constitutive relationship. And the surface currents and Radar Cross Section (RCS) at a single frequency point is computed; In order to achieve high-order derivation work, impedance matrix elements are managed. Then the AWE technique is applied to obtain broadband RCS frequency response of the DNG. A good agreement can be seen between AWE and the exact solution. The computational efficiency is improved significantly.
