Abstract :
The waveguide technique of measuring the complex permittivity of materials is considered. The exact electrodynamical model of the sensor similar to a dielectric tube in a rectangular waveguide is used for a solution of an inverse electrodynamical task that allows reducing the error of measurement results.
