Abstract
The methods of measurement of parameters of dielectric materials of foiled plates have been considered. It has been shown that for "nondestructive measurements" (i.e. without deleting a metal foil from a dielectric plate) the method based on excitation of electromagnetic oscillations in the rectangular plate considered as a resonator, measurement of their resonance frequencies and determination of the relative dielectric permittivity by results of measurements can be used. The appropriate estimated ratios received in the assumption of "magnetic walls" at the plate end faces have been given. On the basis of mathematical simulation in the packet of ANSYS HFSS the validity of this assumption has been shown and also the possibility of use of electrodynamic model of the resonator with "magnetic walls" at end faces for calculation not only resonance frequency, but also a Q-factor and, respectively, determination by results of measurements of both the relative dielectric permittivity and the plate material dielectric loss tangent has been shown.
