电磁屏蔽混凝土性能的数值模拟

Study on Numerical Simulation of Electromagnetic Shielding Concrete

从理论上探讨混凝土对电磁波屏蔽效能的潜在规律，旨在为提高我军营房综合防护能力提供参考数据。研究结果显示：复介电常数、复磁导率虚部对混凝土屏蔽效能的改善在高频波段均明显好于实部；与复介电常数相比复磁导率在低频波段的防护效能则更为突出；而单一组分手性物质对混凝土电磁屏蔽效能的提高作用有限。

This paper is the research of the shielding effectiveness rules of concrete in theory so as to provide reference data for improving all-around defending ability of barracks. The results indicate that imaginary part of complex permittivity and complex permeability to improve shielding effectiveness of concrete is better than real in high-frequency. Compared with dielectric constant, defense ability of magnetic inductivity is more excellent in the low-frequency band. The effect of single component chiral compounds is very limited for increasing shielding effectiveness of concrete.
