Abstract
Employment ofE 0np modes of cylindrical cavity resonator for measurement of electrodynamical parameters of dielectric pipe-shaped materials in millimeter wavelength band is suggested. Dielectric permittivity ɛ and conductivity σ of a sample can be found by measuring the frequency shift and theQ-factor change of the resonator.
Method of “mode basis” is used for the calculation of sample permittivity ɛ and conductivity σ. Measurements were carried out at 8mm wavelength and related calculations have demonstrated use and possibilities of the method in studying the dielectric properties of samples of cylindrical and other forms.
