Abstract :
The electromagnetic analysis of a dielectric loaded rectangular cavity using the 3D transmission line matrix method is presented. It is found that in order to excite all the modes within a frequency range, the field polarisation and location of the excitation brick in the TLM analysis must be properly selected. For the resonator of concern, the results of computation of the first 11 resonant frequencies show excellent agreement with the experimental results
