Abstract

A comprehensive approach to microwave filter design which exploits accurate filed simulations driven directly by a gradient-based minimax optimizer is presented. Challenges of efficiency, discretization of geometrical dimensions, and continuity of optimization variables are reconciled by a three-stage attack: (1) efficient response interpolation; (2) smooth gradient estimation; and (3) dynamic database updating. The design optimization of two microstrip filters illustrates the technique described.<>
