DEVICE FOR DETERMINING DIELECTRIC CAPACITY OF MATERIAL SPECIMEN UNDER EXTERNAL EFFECTS Russian patent published in 2012 - IPC G01R27/26 

FIELD: electricity.

SUBSTANCE: device includes emissive generator, transmitting linearly polarised antennae, chamber for placing flat specimen of the tested material, receiving linearly polarised antennae, receiver, recorder, and is specific for the chamber being provided with flat RF windows for radiation input and output, as well as with either mechanisms or sensors of specimen rotation in the plain of radiation incidence or perpendicular to it. The transmitting antennae is directed with reference to radiation input window under Brewster angle so that the vector of its electrical field is in the plain of radiation to input window, while receiving antennae is directed with regard to the radiation output window under Brewster angle so that its electrical field vector is in the plain of radiation incidence to output window.

EFFECT: increased accuracy of measuring dielectric capacity in wide band when effects from external factors to material specimen are studied.
