Abstract
Methods utilized for investigation of complex dielectric permittivity (ε*) or complex conductivity (δ*) of superionic compounds in the frequency region of 106-8*1010Hz and the temperature range of 100-600K, are presented, as well as used experimental apparatus. At RF (106-1010Hz) a coaxial line method and developed resonance in a coaxial line method was used. The latter makes it possible to increase the sensitivity of measurements. In the microwave region (10-80GHz) the method of partially filled waveguide was used. Some typical complex dielectric permittivity investigation results of NASICON type compounds are shown.
