An approach to include stochastic rough surface scattering into deterministic ray-optical wave propagation modeling

Abstract: A new method to include stochastic rough surface scattering into deterministic ray-optical wave propagation modeling is derived. It can be utilized in conjunction with the concept of ray launching. Similar to the Kirchhoff formulations, the approach is based on a tangential plane approximation, i.e., it is applicable to surfaces with gentle undulations, whose horizontal dimensions are large compared to the incident wavelength. However, in contrast to the Kirchhoff models, which are only valid for either slight… Show more

“…Thus, the Rayleigh roughness parameter Ra r , obtained from the root mean square of the phase variation δφ r , is a useful parameter for estimating the surface electromagnetic roughness. Then, a surface is usually qualified as slightly rough when [23,27,30,31] Ra r < π/16,…”
