Abstract

The shielding effectiveness of conductive cement-based materials to HEMP is analyzed using theoretical method when the materials´ conductivity range 10^-3~10 S/m. The threshold of materials´ conductivity is achieved when their shielding effectiveness increases suddenly. Furthermore, the effect of monolayer and double layer conductive cement shielding rooms on shielding effectiveness to HEMP is discussed and the coupling field is analyzed using FDTD method.
