Abstract

The relative value of the stored energy in the dielectric and that in the surroundings for a cylindrical dielectric resonator in a closed metal cavity was studied using a simple electromagnetic field theory model. The influence of this factor on the measurements of the loss tangents of dielectric samples with different dielectric properties and dimensions at their microwave resonant frequencies was discussed. In addition to the traditional calculation method, a perturbation method with a much simpler computation procedure was also adopted for the energy factor calculation, and its accuracy was compared with that of the traditional method.
