In PM motors, the flux distribution is determined by pole shapes and if the flux distribution is already known, the pole shape desired can be obtained by solving an inverse electromagnetic field problem.

A vector tabu search method and its application in inverse electromagnetic problems;

To release the requirement for tremendously heavy computation resources in the study of electromagnetic inverse problems,a fast global optimizer was proposed,based on the combination of the improved response surface mode(RSM) using compactly support radial basis functions(CS-RBF) and an improved particle swarm optimization(PSO).

Three dimensional electromagnetic forward/inverse problems in magnetoacoustic tomography with magnetic induction;
