Resonant frequencies of natural circular dielectric resonator between its resonant modes has a close range each other, so some desired mode has to be chosen selectively from other modes. Therefore, a circular dielectric resonator with a capability to select the resonant mode is required. This can be overcome by artificially modifying some property of(More)
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(More)
The characteristic of artificial circular dielectric material in microwave engineering is studied. The study encompasses theoretical analysis of artificial circular dielectric, such as anisotropic permittivity characteristics, frequency characteristics and resonance mode in transverse electric mode when the material is used as a resonator encapsulated in(More)
