Abstract :
A new efficient method for the automatic design of multimode resonators is presented. Our approach is based on electromagnetic 3-D modelling performed in the optimization loop. The novelty of the method arises from utilization of some information about the electromagnetic field distribution in the decision about the modification of resonator´s geometry. The field information is processed using perturbation theory
