Information capabilities of resonators with crossed electromagnetic fields as sensing elements of radio-wave transducers

The excitation of crossed electromagnetic fields in a resonator used as a sensing element is treated as one of the possible ways of shaping a fete channels for obtaining the primary information in one sensing element. Relations of natural frequencies of the crossed fields in different types of resonators are given. These relations form a system of equations for determining the parameters (the volume content and dielectric permittivity) of substances that fill the resonator. A generalized algorithm is designed for the measurement of parameters of uniform mixtures. Solutions of a number of essential measurement problems are used as an example for the development of algorithms for transforming experimentally obtained values of the natural frequencies of crossed fields.
