A Composite, Multilayered Cylindrical Dielectric Resonator

The analysis of TE modes in a composite multilayered cylindrical dielectric resonator is presented. All cylindrical dielectric resonator structures which have found some practical applications can be treated as a special case of the structure under consideration. These include: single resonator, double resonator, ring resonator, resonator in microstrip, inhomogeneous resonator and others. A new rigorous method of determining the field distribution and resonant frequency of this resonator is presented. By this method the solution is obtained in a form of successive approximations converging to an exact solution. The analysis is applied in detail to the lowest frequency TE mode of double dielectric resonator.
