abstract = {Whispering gallery mode dielectric resonators are used as
measuring cells to determine the electrophysical
characteristics of materials. It is necessary to choose the
resonator structure possessing acceptable radiation Q-factor
values. Calculation of the radiation Q-factor by analytical
methods is possible for simple symmetric structures only.
Numerical investigations of different-shape leucosapphire
resonators with limiting conducting end plates and without
them are carried out in the Ka-band. The disk resonators
with one conducting end plate are studied experimentally as
well. The effect of tested material sample introduction in
the electromagnetic field on the resonator field
distribution, frequency and radiation Q-factor is shown. The
application opportunity of measurement cells based on such
resonators for determination of the (super)conductor
microwave impedance and permittivity of dielectric liquids
is analyzed. The results obtained can be used for choosing
the resonator measurement cell with a negligible radiation
loss.},
