Evaluation of HEMP Shielding Efficiency of Typical Materials
With the development of information and semiconductor technology,the integration and electromagnetic sensitivity of modern electronic equipment are constantly improving.Especially when facing the High-altitude Nuclear Electromagnetic Pulse(HEMP)with ultra-high field intensity,wide spectrum band and very short rising edge,the electronic equipment can be easily attacked,which affects its the normal operation.Based on various authoritative standards,the HEMP shielding efficiency of typical materials of different types and sizes is tested under different conditions,and the HEMP protection rule of typical materials is analyzed and studied with CST simulation software,which could improve the HEMP protection capability of electronic equipment by using typical materials in the future,and provide important data support for high performance HEMP protection material research.
