The Dielectric Permittivity of Natural Clinoptilolite In The Wide Range of Frequencies

Abstract

The dielectric permittivity of natural clinoptilolite has been measured in the wide frequency range up to microwave frequencies (4,5∙10¹⁰ radn /s)  It describes in detail the method of measurements of the real part of dielectric permittivity by means of partly filled rectangle waveguide. Obtained result of ε^ı =1,53 complements the results obtained previously in the range up to 10⁶ Hz and makes it possible to interpret the frequency dependence of the dielectric permittivity with the help of the model of relaxation oscillator.

Keywords: natural zeolite, clinoptilolite, the dielectric permittivity, microwave frequencies, partly filled rectangular waveguide.
