Analysis of shielding effectiveness of reinforced-concrete in high power electromagnetic environment

The finite-difference time domain (FDTD) method is used to analyze shielding effectiveness of the infinite wire-mesh reinforcement, reinforced-concrete layer and concrete-only layer in a high power electromagnetic environment. Our research takes into account all the factors affecting shielding effectiveness (jointing of reinforcing steels' cross points, connection of the reinforcement hoops and natural defensive layers). Numerical examples concerning the analysis are given in this paper.
