Abstract :
An efficient computer system, for automatic synthesis of passive microwave structures of novel geometrical shapes, based on 3D FD-TD electromagnetic simulation was developed. The first robust multilevel hybrid optimization which allows unrestricted evolution of an arbitrary circuit shape is presented. Two designs of unique microwave structures illustrate our technique.
