Formulation of the problem. It is necessary to determine the wavelength at which the maximum energy of the electric field of the main slow wave H10 of a rectangular waveguide with a dielectric plate located in the E-plane of the waveguide is achieved.

Target. The purpose of this work is to determine the optimal way to achieve the maximum permissible level of electric field energy in a dielectric plate located in the E-plane of a rectangular waveguide, which makes it possible to intensify the heating process of sheet materials in waveguide-type microwave devices.

Results. As a result of the study, the wavelength at which the maximum energy of the electric field of the main slow wave H10 of a rectangular waveguide with a dielectric plate located in the E-plane of the waveguide in the dominant wavelength range is achieved was determined.

Practical significance. The results obtained in the work make it possible to formulate practical recommendations in the form of optimal values of the electrophysical parameters of a waveguide with a dielectric plate, at which technologies for microwave drying of valuable wood veneers, parquet boards, printed fabrics, film and sterilization of surgical instruments are most effectively implemented in terms of electromagnetic energy consumption.

The study was carried out with financial support from the Russian Science Foundation within the framework of scientific project No. 22-19-00357.
