MATERIAL DIELECTRIC PROPERTIES MEASURING METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC G01R27/26 

FIELD: electricity.

SUBSTANCE: invention relates to the materials dielectric permittivity and the dielectric losses angle tangent measurement. In the free space, the material sample is placed at the Brewster angle, in the frequency range measuring the passed wave power and phase and from the passed wave phase change in the frequency band, calculating the sample material dielectric permittivity frequency dependence value by the formula, calculating the Brewster angle by the dielectric constant at each set frequency, after which rotating the material sample on the support, establishing the calculated Brewster angle, determining the sample material dielectric losses angle tangent by the reflected wave phase angular dependence gradient. Material dielectric properties measuring method advantages implementation device, including transmitting antenna, receiving antenna, receiving passed through the material sample wave, receiving antenna, receiving reflected from the material sample wave, a support for the material sample securing, connected to the control computer SHF-meter, characterized in that receiving the reflected wave receiving antenna is located on the coaxially mounted with the sample material support platform, with possibility of their rotation around the axis, wherein the platform and the stand are equipped with the rotation angle sensors and motors with control units, connected to the control computer, and the receiving antennas are connected to the SHF-meter through the switch, connected to the control computer.

EFFECT: technical result consists in increase in the materials dielectric properties measuring accuracy in the wide frequency band.
