英文摘要：

This paper presents a new design technique for filters. It is based on the improved aggressive space mapping method. Firstly, the partial derivative matrix with a single variable was used as an initial mapping matrix. Because of introduction of the Cauchy method in parameter extraction process, the speed of parameter extraction was accelerated without loss of accuracy. Finally, to confirm the design method presented in this paper, a coax filter with four resonators was designed and simulated using HFSS software. The agreement between simulated and theoretical results is good.
