Abstract

In this paper, predictions from the small-slope approximation (SSA), the advanced integral equation model (AIEM), and the reduced third-order local curvature approximation (RLCA3) theories of rough surface scattering are compared with each other and with predictions obtained from numerical simulations for dielectric surfaces with Gaussian and exponential correlation functions. A discussion of the results obtained is provided, along with plans for continued investigations.
