High-Frequency Methods of Measuring Dielectric Properties of Condensed Substances Behind Shock Wave Front,

Abstract

Permittivity and dielectric losses are closely related to the microstructure of the dielectric, the magnitude of the dipole moment of the molecules, relaxation times of polarization, etc. It is interesting to use dielectric measurements in shock compression experiments to explain the mechanism of the simultaneous effect of high dynamic pressures and temperatures on a substance. Proposed in the present report are two high-frequency methods of measuring the dielectric properties of condensed substances behind a shock wave front - the amplitude method and the oscillatory circuit method. The idea of the experiments was to measure the capacitance of a plane capacitor filled with a dielectric under conditions of single-stage shock compression.
