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...

The backscattering signal at small grazing angles is very important for vehicle re-entrance and missile tracking applications. It is also useful in FTIR grazing angle microscopy. Recently, we performed an experimental study of the far-field scattering at small grazing angles, especially the enhanced backscattering at grazing angles. For a randomly weak rough dielectric film on a reflecting metal substrate, a much larger enhanced backscattering peak is measured.
