Abstract
It is developed a measuring stand, providing along with the developed software for performing measurements and statistically processing the results of measurements of the permittivity tensor components and dielectric losses of single-axis crystals with a tetragonal type of symmetry in the microwave band without destroying the measured objects. The measurement error while measuring permittivity of isotropic dielectrics is about 1%, the permittivity tensor components – is not exceeding 3%, the dielectric loss factor – of 15%. The sensitivity to variation of the permittivity value (depending upon the bandwidth) is 400 to 800 ÌHz per unit of ?.
KEY WORDS:anisotropic crystal, dielectric, measurement, loss factor
