Efficient and Fast Analysis of SIW Microwave Devices Using the Multiple Multipole Technique

Abstract

An efficient and fast two-dimensional method is presented using multiple multipole program (MMP). The proposed method is applied to analyze two different substrate integrated waveguide structures. A two-port post filter and a three-port power divider are studied and the results show an excellent agreement with the commercial software results. It can be seen that our method is 4.7 times faster for SIW post-filter and 7.9 times faster for power divider than the commercial software.
