Length Scales Analysis of Wave Scattering from Rough Surfaces
... There are three length scales which scaling behavior between them play role in rough surface scattering, wave-length (λ) of the incident wave, the roughness (σ) and the correlation length (ξ) of the surface. In this work we show the effective role of the correlation length in surface scattering. Up ...
