“…When estimating the EM field hazard inside the industrial facilities, a cylindrical EM radiation hazard map (see Fig. 6) may be used, modeled in accordance with the technology developed by the authors [6,7]. Every pixel of the cylindrical image accounts for the parameters of the EM field inside the cylindri-cal zone (with some predetermined radius based on the industrial requirements) around the pixel.…”

“…Thus, the significance of the work lies in the principles of converting EM portraits (pictures of the distribution in space of the EM field components) [6] into pictures of the danger of EM radiation (in the form of maps of the allowed time to stay in an EM field) [7]. The transformation is performed on the basis of the results of the systematization of the methods for determining the permissible residence time in the zone of EM radiation, taking into account each component of the EM field.…”

This article deals with the visualization of the intensity of the electromagnetic field in a production room with various electrical equipment. To assess the electromagnetic environment under the simultaneous influence of a set of electromagnetic field sources (radiation sources), a new approach is proposed, based on the formation of electromagnetic portraits and combined pictures of the electromagnetic radiation danger. Electromagnetic portraits and hazard pictures are obtained from the results of visual diagnostics of hazardous areas of external surfaces of radiation sources, a limited number of measurements at control points, and modeling of the electromagnetic field, taking into account the possibility of simultaneous influence and amplification of the resulting action of several radiation sources. The technical implementation of the proposed approach is provided by the developed intelligent system that allows real-time automation of the control of the electromagnetic environment and the formation of hazard patterns in the zones of exposure to electromagnetic radiation at various frequencies (up to 3 THz), taking into account the electromagnetic field overlay. A complex estimation of the hazard level is combined from the separate hazard of each electromagnetic field component the briefly described mathematical apparatus.

“…Therefore, more and more attention has been paid to the study of electromagnetic environmental effects. This study area has experienced a transition from effect modeling [15,16] to effect evaluation [17] and prediction [18] and from qualitative to quantitative [19,20] study. We believe that the study of the evaluation/prediction of electromagnetic environmental effects should not be limited to effects on a certain object.…”

With the increasing complexity of the electromagnetic environment, existing electronic systems and various equipment are greatly threatened. The study of the assessment of the effects of the electromagnetic environment has attracted more and more attention in the academic field and industry. In this review, the definition of the electromagnetic environmental effects assessment could be classified into two categories: objective and subjective equipment electromagnetic environmental effect assessments. Studies on both are comprehensively reviewed. The electromagnetic environmental effect assessment models are described and analyzed. The effects evaluation models mainly calculate the electromagnetic environmental effect index by various weighting, probability, and normalized interference level methods. However, each proposed model has certain limitations, so it cannot deal with all the electromagnetic interference effects. Therefore, a comprehensive evaluation model for complex electromagnetic environmental effects has not yet been established. Recent studies have shown that neural networks can be used to improve the adaptability of evaluation models in electromagnetic environments. The evaluation result of the normalized interference level method is more consistent with the actual work efficiency. The combination of the two can unify the objective and subjective assessments, which is of great significance to the improvement of the consistency and accuracy of the results of the effects evaluation of the electromagnetic environment. Accordingly, challenges for future research are revealed, which plays a vital role in the development of electromagnetic environmental effects research and provides a reference for researchers.

Computer simulation of the electromagnetic environment makes it possible to determine the sources of the electromagnetic field and radiation at the object under study, accelerates the process of determining the degree of danger of the electromagnetic environment, forms pictures of the distribution in space of the components of the electromagnetic field and creates maps of the permissible time of human stay. Free software (openEMS, MEEP) significantly simplifies the solution of these tasks. The article considers the issues of assessing the adequacy of computer models of the distribution of electromagnetic field components formed using these modeling packages. The results of experimental measurements and computer simulation of the electric field at frequencies of 50 Hz, 30 kHz, 3 MHz, 30 MHz and 50 MHz are presented. The results of measurements and computer simulation of the electromagnetic field at frequencies of 800 MHz, 25 Khz and 40 GHz are presented. The adequacy of modeling the components of the electromagnetic field using openEMS and MEEP, sufficient for practical application, has been confirmed.
