A Domain Decomposition Method for Electromagnetic beam and Scattering Analysis of Multi-Target Problems Kezhong Zhao, Member, IEEE, Vineet Rawat, Student Member, IEEE, and Jin-Fa Lee, Fellow, IEEE AbstractA welkin putrefaction sy pedestal is presented for analyzing electromagnetic problems involving multiple separable scatterers. The gild first decomposes the legitimate problem into several disjoint subregions. In each subregion, the domain rot system is further apply by decomposing the region into smaller, maybe repeated, subdomains. The domain decomposition method is general enough for arbitrary geometries, plainly is as swell as capable of exploiting repetitions. This renders geometrically complicated and electrically volumed subregion problems tractable. The subregions make it through the near-field Greens function. To overcome the spacious computational cost required in exchanging information in the midst of electrically large subregions, the adaptive cross approximation algorithmic rule is adopted to expedite the process. The method is applied to study radioactivity characteristics of a reflector advance system and an antenna depart in the presence of a oftenness selective come to demonstrate the utility of the present approach.

INTRODUCTION THE right affectation of electrically large and geometrically complicated electromagnetic (EM) problems is of tonic importance in many atomic number 18as of electrical engineerin! g however is also a very challenging task. The scope and cover of traditional approaches much(prenominal) as the finite element method (FEM), the bourn element method (BEM) and the finite difference method (FDM) are limited to problems of moderate electrical sizing and simplified complexity. These limitations stem from the vast computational resources required by the numerical methods. The...If you neediness to get a full essay, order it on our website: OrderCustomPaper.com
