Simulation & Optimization of a Dual-Mode Four Cavity Elliptic Waveguide Filter

This paper is about the simulation and optimization of a bandpass dual-mode circular four cavity elliptic waveguide filter using High Frequency Structure Simulator (HFSS). Besides the filter design, the tuning of this filter is a wearisome job to achieve the optimum response. An optimization scheme is presented to efficiently tune this filter using HFSS.
