A distinctive feature of emerging technology for decontamination of medical instruments is the prevailing effect of electromagnetic field energy on the microflora. The processes underlying this technology have shown to be poorly understood, which predetermines the relevance of this study. The objective of this work is the study of the factors influencing the strength of the electromagnetic field near the surface of medical instruments irradiated with microwave energy. Mathematical models have been developed that describe the processes of propagation and scattering of electromagnetic waves near a metal surface covered with a layer of water. The features of the field behavior inside the water layer with variations in its height and temperature are revealed. The conditions for the formation of the maximum field strength tangential to a metal surface are found. The simulation results made it possible to formulate practical recommendations for the implementation of the technology of microwave sterilization of surgical instruments.
