| Research Abstract |
We have proposed a discrete ray tracing method to numerically simulate propagation along random rough surface and back scattering from it with a good accuracy. We have also developed an algorithm to generate various types of random rough surfaces. It has been demonstrated that the ensemble averages of electric field distributions can be described in a simple fashion based on the 1-ray or 2-ray model with amplitude modification factor and propagation order of distance.
