A Novel Method for Tailoring the Electromagnetic Radiation Emission Limits of Equipment in Complex System

Abstract

The trend toward integration in systems has led to the unpredictability of electromagnetic compatibility within the system. Fixed radiation emission standards struggle to meet the diverse and complex requirements of specific scenarios, making it essential to design or adjust emission limits for specific equipment. To address this issue, this article investigates a method for tailoring the emission limits standard RE102 of radiation equipment in complex systems that include multiple radiating and sensitive equipment. We establish a radiation coupling network model within the system and propose a solution based on the affine-scaling interior-point method for solving the emission limit indicators. This method abstracts the problem of tailoring radiation emission limits into a single-objective optimization problem. We establish a design cost calculation model for each piece of radiation equipment, with the total system design cost as the optimization objective, to obtain the optimal solution under constraints. Finally, through case design and testing involving multiple radiating equipment and sensitive equipment, the test results demonstrate the effectiveness and reliability of the proposed novel method in different scenarios.
