Effect of material thickness on resonance characteristics of anisotropic artificial circular dielectric resonator

In the case of the artificial circular dielectric resonator which is encapsulated in a circular waveguide, the resonance characteristic is determined not only by a resonator thickness but also by a novel anisotropic permittivity value and a radius of a circular waveguide. In this paper, the relationship of its parameters is calculated and analyzed. The calculation is done by using the mathematical formulation which is derived from Maxwell's equations with proper boundary condition. The research is focused on the influence of the resonator thickness to the TM resonance characteristics of artificial circular dielectric resonator. The results show, the ability of novel anisotropic in p direction increase due to a radius of a circular waveguide enhancement for TM0, wave mode, whilst, the ability increase due to a radius of a circular waveguide reduction for TMU wave mode. A novel permittivity in p direction is effective reduce the resonant frequencies for thin resonator thickness.
