Abstract The creation of new composite materials with specified radio-frequency properties is often carried out using small-sized inclusions, while the polarizability parameters of these small bodies in electric and magnetic fields play a significant role. The paper considers the possibility of measuring the polarizability of small components of the composite in an open quasi-optical resonator. It is shown that the values of the electric and magnetic polarizability of small particles can be estimated from the shifts of the resonant frequencies that arise when a small scatterer is placed in the resonator.

The seafarers carried out the professional activity in a complex electromagnetic environment (EME), with technical means, structural materials, depending on the purpose of the watercraft, architectural features, and vessel classification. There are static electric fields, permanent magnetic and low-frequency electric and magnetic fields on ships. Marine radio-electronic means (REM) creates Electromagnetic fields (EMF) of the radio frequency range that provide communication, the safety of navigation and operation, and solving navigation problems. According to the documents of the sanitary legislation, specialists carry out control of the maximum permissible EMF levels for watercraft and marine structures at the design stage of the vessel by calculating the intensity of electromagnetic fields during commissioning, instrumental control of EMF levels. There are new technical means in modern automated vessels of various types and purposes that create electromagnetic fields in the crew's stay zones, which makes it urgent to improve regulatory and methodological documents in the area of ensuring the electromagnetic safety of the team and passengers. The study aims to develop proposals for regulatory, methodological, and hardware control over compliance with the maximum permissible levels of electromagnetic fields on ships to ensure the electromagnetic safety of the crew. Generalization of materials of own research of EME on ships, systematization of sources of electromagnetic fields. Analysis of regulations in occupational safety and health for the protection of the crew from the effects of EME, methodological documents on the calculation forecasting, and instrumental determination of the levels of electromagnetic fields. Experts have revealed that there are electromagnetic fields of a wide frequency range in the premises of ships and on open decks. The study showed that electromagnetic fields of a wide frequency range are created in the premises of ships and on open decks. Indoors, the most significant is the impact on the crew of electric and magnetic fields with a frequency of 50 Hz created by the ship's electric power systems. In addition, on open decks (at workplaces and in crew recreation areas), the protection of the crew from EMF antennas of the radio frequency range is relevant. Therefore, it is necessary to develop methods for calculating the prediction of EMF levels and improve the means of measuring electromagnetic fields on ships. The most common sources of EMF in the crew's stay areas are radio communication and radar facilities, ship's electric power systems. The task of developing a methodological document on the calculated prediction of EMF levels in rooms and on open decks at the design stage of ships is urgent. In addition, it is necessary to develop devices-meters of electromagnetic fields for instrumental monitoring of EMF levels in actual operating conditions of the vessel.
