Currently, one of the actual tasks of using microwave sterilization is to increase the number of simultaneously processed instruments (surgical, cosmetic, etc.) while maintaining a minimum processing time (several minutes), as well as the mobility and compactness of the sterilizer.

The objective of the present work was to determine on the basis of mathematical modeling the electrodynamic and geometric parameters of the operating resonator chamber of increased size and the corresponding container for the instruments of a microwave sterilizer, the source of electromagnetic radiation of which is paired magnetrons with a significantly high generation power. Based on the equations of electrodynamics, a design of resonator chamber of increased volume (66 l) has been proposed, which makes is possible to increase the volume of the container and the number of processed standard instruments by a factor of two or more with a predictable (taking into account the increases value of the tangential component of the electric field) sterilization time within 5...7 minutes.

The design of a high-power microwave sterilizer proposed in the present study makes it possible to speed up the decontamination process and increase the number of medical instruments simultaneously irradiated with electromagnetic energy.
