Using Improved Domain Decomposition Method and Radial Basis Functions to Determine Electromagnetic Fields Near Material Interfaces

Abstract

This paper presents a novel approach for solving problems of electromagnetic fields near material interfaces. This novel approach is based on combination of radial basis functions (RBF) and improved domain decomposition (DD) method. We discuss three radial basis functions in this condition, compared with common domain decomposition method in two subregions example. To get the same precision, improved method has extended the range of parameter C in radial basis functions. We also apply the method to the analysis of heterogeneous multi-subregions example, a turbo generator rotor winding. The simulation results demonstrate good agreement with practice, showing the adequacy of the proposed methodology for electromagnetic analysis.
