Characterization of the resonant and coupling parameters of dielectric resonators of NRD-guide filtering devices

The design of millimeter-wave filtering devices using dielectric resonators of various shapes in nonradiative dielectric (NRD) waveguides is considered. By developing different approximate and rigorous theoretical methods, the resonant and coupling properties (frequencies, field configuration, unloaded and loaded quality factors, scattering parameters, etc.) are modeled and implemented in an adaptive code. Experimental comparison through suitable measurements are performed to validate the theoretical and numerical results.<>
