Abstract: | Statistics of electromagnetic rays in a random medium are studied numerically by the Monte Carlo method. Two dimensional random
surfaces with prescribed correlation functions are used to simulate the random media. Rays are then traced in these sample
media. Statistics of the ray properties such as the ray positions and directions are computed. Histograms showing the distributions
of the ray positions and directions at different points along the ray path as well as at given points in space are given.
The numerical experiment is repeated for different cases corresponding to weakly and strongly random media with isotropic
and anisotropic irregularities. Results are compared with those derived from theoretical investigations whenever possible. |
