Abstract
With the rapid development of modern electrical engineering, the problem of electromagnetic interference is increasingly prominent, which poses a serious threat to the stability and safety of equipment. To solve this problem, this paper systematically studies the application of electromagnetic shielding technology in electrical engineering and its optimization method. The study aims to propose an efficient and economical electromagnetic shielding solution through in-depth analysis of the characteristics, structural design and performance evaluation of electromagnetic shielding materials. Based on the method combining theoretical modeling and experimental verification, this paper first explored the influence mechanism of different shielding materials on electromagnetic wave absorption and reflection, and then designed and tested a new composite shielding structure, which significantly improves the shielding efficiency. The results show that the proposed composite shielding scheme shows excellent shielding performance in high frequency band with good thermal stability and mechanical strength. In addition, this paper innovatively introduces the multi-scale simulation technology to predict the shielding effect and guide the actual engineering design, which greatly reduces the test cost and improves the research and development efficiency.
