Abstract. Electromagnetic signals and waves accompany us in everyday life; the information transmitted by them allows us to use mobile phones, radios, and televisions. However, electromagnetic waves can also be used for undesirable purposes, such as eavesdropping or unauthorized access to information. Radio-absorbing materials (RPMs) are used to protect against such threats. The materials and coatings used for shielding vary greatly in their properties, shielding ability, and price. The determination of the tactical and technical characteristics of a protective shielding radio-absorbing coating based on polymer carbon-containing matrices with ferromagnetic nanoparticles was based on the development of a threat model for the information of a dedicated room and the physical-chemical properties of the material. In conclusion, shielding radio-absorbing coatings based on polymeric carbon-containing matrices with ferromagnetic nanoparticles have a number of advantages over traditional materials. They have a wide frequency range, high corrosion resistance, mechanical strength, resistance to radiation, and compatibility with other materials. The installation of such a coating is easy and environmentally friendly. Low weight and flexibility allow the coating to be adapted to any surface shape. The temperature range and absorption efficiency of this RPM make it versatile for use in a variety of industries. The thickness and lightness of the material simplify the installation process and do not weigh down the structure.
Key words: shielding coating, threat model, polymer matrix, radio-absorbing coating, ferromagnetic nanoparticles, radio frequency signals, tactical and technical characteristics, carbon-containing matrices
