Abstract

An inverse design in electromagnetic method based on the topological derivative approach is presented. Topological derivative method is used to measure the sensitivity of a given functional with respect to an infinitesimal perturbation in a domain. The topological derivative concept has been successfully applied in many relevant fields such as geophysics, multi-scale material design and inverse problems. In this work, to design the electromagnetic devices an objective function dependent on the scattering parameters is considered. Finally, numerical results are presented to illustrate the performance of the optimisation approach.
