Calculation of dielectric resonators with complicated constitutive parameters

A novel approach for calculation of resonant frequencies of dielectric resonators in waveguides or cavities is presented. The resonant sample may be made from different materials: high-permittivity dielectrics, magnetic materials, chirals or general bi-anisotropic materials. The resonant frequencies of high-permittivity dielectric resonators in a cylindrical cavity are calculated and compared with the literature to validate the proposed method. Numerical results of chiral and Faraday chiral resonators are also given
