Research of electromagnetic shielding within buildings near transmission line based on FEM

In recent years, the impact of electromagnetic radiation on the lives and environment of urban residents is becoming increasingly apparent. And in the meantime the rapidly growing requirement of people´s life quality makes that the electromagnetic environmental problem near high voltage transmission lines is gathering more and more concern. Based on the study of the Finite Element Method, and through simulating and analyzing the electromagnetic character and electromagnetic shielding within building near extra high voltage transmission line, this paper makes use of the Control Variable Method to comprehensively study all the factors that may have an influence on shielding effectiveness. Finally, it puts forward practical, feasible and effective approaches of the electromagnetic shielding scheme selection.
