Abstract

Abstract

Considering region segmentation, message transmission, load balancing, synchronization, etc, the paper presents a parallel finite-difference time-domain algorithm to calculate the electromagnetic scattering at randomly rough surface and applies the algorithm to high performance parallel computers. Theoretical analysis and simulation show that, the algorithm can calculate electromagnetic scattering at large-scale random rough ground fast and efficiently. Its correctness and feasibility are verified by comparison with analytic method under the same conditions, and its large-scale results are better to reflect the ground statistical characteristics.
