Shape Optimization Methods for the Design of Microwave Circuits and Antennas

Shape optimization techniques allow improving the performance of a device by changing its geometrical or topological parameters, pushing the limits of classical designs. Like any optimization method, shape optimization techniques converge towards an optimal solution, based on the computation of a cost function related to the response of the device (S parameter, directivity …) after modifying a set of parameters that control the size, the boundary or the topology of its components in the optimization domain.
