Paper Abstract

This paper discusses a new formulation of the Fast Multipole Method of 3D topography scattering in the physical-optics approximation. The novelty of this formulation lies in the use of generalized Sommerfeld integrals to represent the vector multipole waves. This technique allows 3D reflective-notching simulation to be done on an ordinary workstation in O(N3/2) time, where N is the number of nodes on the surface of the topography. Simulation results for 3D topography with different slope angles are presented. The simulated reflective-notching effects were found to be consistent with a ray-optics model.
