Using the particle swarm evolutionary approach in shape optimization and field analysis of devices involving nonlinear magnetic media

Extensive efforts have been long directed towards the development of shape optimization methodologies for electromagnetic devices. In case of devices involving nonlinear magnetic media, this optimization process becomes more complicated. This paper demonstrates how shape optimization and field analysis of such devices may be carried out efficiently and conveniently using the particle swarm evolutionary approach and without the involvement of other computational tools. Details of the proposed approach, its application to different electromagnetic devices, and comparisons with finite-element computations are presented in the paper.
