Use of supercomputers to evaluate singly and multiply scattered electromagnetic fields from rough surfaces
Abstract
Full wave expressions for the singly and the doubly scattered electromagnetic fields from onedimensional rough surfaces are computed. The singly scattered like and crosspolarized fields are expressed in terms of onedimensional integrals. However, the doubly scattered full wave solutions are expressed in terms of two and threedimensional integrals. To compute the like and the crosspolarized multiple scattered fields a supercomputer must be used. The results indicate that double scatter in the backward direction is significant for near normal incidence when the mean square slopes of the highly conducting rough surfaces are larger than unity.
