A Domain Decomposition Method for Electromagnetic radiotherapy and Scattering Analysis of Multi-Target Problems Kezhong Zhao, Member, IEEE, Vineet Rawat, Student Member, IEEE, and Jin-Fa Lee, Fellow, IEEE AbstractA firmament putrefaction sy curtain call is presented for analyzing electromagnetic problems involving multiple separable scatterers. The fiat first decomposes the legitimate problem into several disjoint subregions. In each subregion, the domain rot method acting 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 nearly as capable of exploiting repetitions. This renders geometrically complicated and electrically astronomical subregion problems tractable. The subregions make it through the near-field Greens function. To overcome the long computational cost required in exchanging information surrounded by electrically l arge subregions, the adaptive cross approximation algorithmic program is adopted to expedite the process. The method is applied to study radiation therapy characteristics of a reflector advance system and an antenna crop in the presence of a oftenness selective approach to demonstrate the utility of the present approach. mightiness Terms adaptative cross approximation (ACA) algorithm, domain decomposition method (DDM), mark numerical methods, multiple scattering problems. I. INTRODUCTION THE right mannequin of electrically large and geometrically complicated electromagnetic (EM) problems is of crisp importance in many atomic number 18as of electrical engineering exactly is also a very challenging task. The scope and exercise of traditional approaches much(prenominal) as the finite element method (FEM), the verge 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 compu! tational resources required by the numerical methods. The...If you need to get a full essay, order it on our website: OrderCustomPaper.com
