METHOD FOR DETERMINING DIELECTRIC PROPERTIES OF DESTRUCTIVE MATERIALS DURING HEATING Russian patent published in 2024 - IPC G01R27/26 G01N25/16 

FIELD: measuring instruments.

SUBSTANCE: method for determining dielectric properties of destructive materials at microwave frequencies. A method is proposed for determining the dielectric properties of destructive materials when heated, including tuning a resonator without a sample and with a sample into resonance at the resonant frequency, heating the resonator with and without a sample, measuring temperature changes in the length of the resonator and determining the temperature dependence of the dielectric constant of the sample, where the sample consists of a destructive material. Material placed in a quartz glass cuvette, closed with a quartz glass lid.

EFFECT: increase in the accuracy of determining the dielectric properties of destructive materials in a hollow cylindrical resonator when heated, by reducing the ingress of combustion products into the measuring volume of the resonator and preventing the ingress of combustion products onto the conductive surface of the piston.
