Abstract:

In the theory of Physical Optics the field scattered by a curved reflecting surface S is represented by an integral whose numerical evaluation is difficult. Two methods for calculating this integral are discussed A Monte Carlo method and the method by Facet Decomposition. The first is limited by round-off error whereas the second is limited by computer storage and CPU running time. The Facet Decomposition method is exact when S is flat, and is superior to the Monte Carlo method when S is only slightly curved according to a certain criterion. Author
