不完全屏蔽腔体辐射耦合电场增强效应防护方法
Protection method of radiated coupling electric field enhancement effect for the incomplete shielding chamber
摘要
Abstract
Aiming at the requirements of the electromagnetic radiation protection of the weapon enclosure,we studied the protection method of electric field enhancement effect caused by aperture and penetrating conductor coupling in accordance with the formation mechanism of radiated coupling electric field enhancement effect for the incomplete shielding chamber.The influence of loading absorbing material,partitioning chamber and fixing penetrating conductor conduit on the electromagnetic coupling of the incomplete shielding chamber were calculated.The research results indicate that the electric field enhancement effect caused by the chamber resonance can be reduced by loading absorbing material in shielding chamber.The protection effect of the absorbing material is much higher when the same absorbing material places on the location of the high intensity electric field.The resonance frequency of the shielding chamber can be enhanced by partitioning the shielding chamber,and the electromagnetic coupling capacity can be substantially reduced on the most position of the chamber.The penetrating conductor coupling capacity can be reduced by fixing penetrating conductor conduit,and the electric field enhancement effect caused by the induced current resonance can be reduced.The longer the length of the penetrating conductor conduit is,the higher the protection effect will be.关键词
