Scattering of electromagnetic waves from the random surface of a left-handed medium
Recently a physical medium was fabricated in which both the effective permittivity () and the effective permeability µ() are simultaneously negative over a restricted frequency range. Thus, in t...

Thebackscattering signal at small grazing angles is very important forvehicle re-entrance and missile tracking applications. It is also usefulin FTIR grazing angle microscopy. Recently, we performed an experimentalstudy of the far-field scattering at small grazing angles, especiallythe enhanced backscattering at grazing angles. For a randomly weakrough dielectric film on a reflecting metal substrate, a muchlarger enhanced backscattering peak is measured.
