A New Approach for the Coupling Identification in Dielectric Resonators Filters

A Method has been identified for the determination of the nature of coupling between individual dielectric resonators. It is based on electric field orientation in the dielectric resonator. The method is appropriate for the coupling identification in complex filter design topologies, such as filters involving finite number of transmission zeros. The suggested method is easy and direct to analyze the coupling nature between dielectric resonators and can be applicable to any design topology involving dielectric resonators.
