Abstract :
Dielectric resonators are used widely for determination of materials complex permittivity. Whispering gallery mode (WGM) dielectric resonators have high quality factor values and this make it possible to achieve a high measurement precision [1]. In order to research the biological liquids in small it is reasonable to use dielectric resonators with small nonhomogeneities where the liquids under test are placed, for example the resonator with an additional thin layer [2] or with a capillary [3]. The shortcoming of these resonators is a difficult making.
