讲座主题:埋在随机粗糙地表下三维物体的电磁散射(Electromagnetic Scattering of Three-Dimensional (3D) Objects Embedded in a Half Space with Random Rough Surface)
讲座介绍:A Monte-Carlo multidomainpseudospectral time-domain (MPSTD) algorithm is developed for the analysis of scattering from a two dimensional (2D) and three dimensional (3D) object buried below a random rough surface separating two half spaces. In the development, special attention is paid to the 3D computation domain decomposition, PML derivations, filtering technique and subdomain mapping involving the random rough surface as well as the subdomain patching along the rough surface. The Mote-Carlo MPSTD algorithm is then employed to determine the scattering of objects of various shapes and electromagnetic properties; embedded in the lower half space with different permittivity and the roughness of the random rough surface may vary. Sample numerical results are presented, validated, and analyzed....
