Abstract:

The use of symmetrical H- and E-modes and asymmetrical E-modes in a longitudinally anisotropic dielectric cylinder with metal mirrors at the ends to measure its permittivity and dielectric loss tangent is considered. It is shown that the method has wider possibilities compared with the IEC-61338 recommendations. The results of a measurement of the dielectric parameters of a number of materials in the 2–78 GHz frequency band, including the permittivity tensor of sapphire, are presented.
