ABSTRACT
It is informed that recent studies conducted by N.T. Cherpak reported some measurements on the frequency shift and the merit factor of a whispering gallery dielectric resonator loaded by water and other materials. The obtained results appear of interest, since the dielectric properties of the samples can be potentially determined. It is concluded that the experimental results reported are well reproduced without invoking a negative dielectric constant for water. A positive shift of the resonance frequency of quasi-TM modes is expected in this geometry for any sample having extremely high dielectric losses.
