Abstract

Based on the Method of Moment and the volume integral equation, a general technique for analyzing the electromagnetic shielding properties of rectangular concrete enclosures is presented. After deriving the volume integral equation for the internal electric field, we proceeded to solve the equation numerically by MOM. The comparison between the calculation results of this paper and calculation results of other paper shows that the method is effective. The approach can be used to analyze the shielding effectiveness of protection cell in substation, and the shielding effectiveness of a concrete protection cell model is calculated in this paper.
