Applicability of Cavity Modeling Technique to Analyze Complex Waveguide Structures Involving Cavity Cross Couplings

This paper investigates the applicability of cavity modeling technique to analyze complex waveguide structures, involving cavity cross-couplings. Some all resonator based waveguide diplexers with cross-coupled cavities have been considered for analysis purpose. Previously cavity modeling technique was used to analyze different waveguide based networks. But here, for the first time, the cavity modeling technique has been tested to analyze waveguide structures with cross coupled cavities. The results obtained through the theoretical analysis and simulation have been compared with literature available data to conclude the applicability. The cavity modeling technique also has been applied in the proposed work to study the field propagation inside the network, for the first time.
