Modeling of cylindrical dielectric resonator filters by a 2D radial FEM approach

An efficient full-wave modelling of cyUndrical dielectric resonator filters in rectangular waveguide is presented. The method is based on the Generalized Admittance Matrix (GAM) computation by an efficient 2D radial FEM technique, combined with analytical methods. Comparison with available results in the literature confirm the accuracy and efficiency of the method described.
