Abstract

The article is devoted to the modern study of the influence of electromagnetic radiation on computer systems and the consideration of mechanisms for tracking the effects on low-voltage conductors. The purpose of the article is to determine practical aspects of countering harmful electromagnetic effects on communication systems and computer systems. Methodology. During the study, calculations were made of the influence of electromagnetic radiation on lowvoltage systems, in particular computer systems, as well as its harmful effects on telecommunications facilities. The capabilities and significance of radiation protection measures were analyzed to determine their optimal volume, necessary to ensure stable operation of such systems. The proposed approaches make it possible to adapt protective methods in accordance with the nature and scale of electromagnetic threats, taking into account the characteristics of computer systems. The scientific novelty of this study is as follows: new mechanisms of interaction of low-current systems were considered, previously unexplored mechanisms of influence of electromagnetic radiation (EMR) on low-voltage electrical signals were analyzed, innovative approaches to shielding and filtering of EMR influence were substantiated and considered, the use of materials with new electromagnetic properties (for example, metamaterials) to increase the effectiveness of protection was justified. Regarding practical aspects, the effectiveness of traditional and new protection methods in real operating conditions was assessed. Given the constant development of new technologies, various mechanisms of this interaction were considered, such as electromagnetic induction, noise radiation and the general influence of the electromagnetic field on the parameters of electrical circuits and microcircuits. Particular attention is paid to practical aspects of counteracting the negative impact of electromagnetic interference. An important direction in the study of this topic is the consideration of modern methods of shielding computer systems, filtering harmful signals and design solutions that increase the resistance of electronic devices and lowvoltage systems to the influence of electromagnetic radiation of various frequencies. The contribution of M. A. Richards, V. A. Holmes to the theory of radar, conversion of interfering electromagnetic signals, algorithms for their processing and application in electronic low-current systems is described. Conclusions. According to the results of this study, certain methods were recommended for the protection of low-voltage systems, such as: shielding with materials with high electrical conductivity, LC – filtration, the use of absorbing coatings, the use of active systems that generate antiphase signals to suppress unwanted radiation, etc. The study demonstrates the successful application and systematization of knowledge regarding the impact of electromagnetic interference on computing and telecommunication systems and provides information that can form the basis for further research and development in this area of physics.
