Research on the New Multilayer Composite Lightning Electromagnetic Shielding Materials

According to the characteristics of lightning electromagnetic pulse (LEMP) in information systems, the new multilayer composite electromagnetic shielding materials are utilized for the effective protection of the lightning hazards. The lightning protection mechanism and the characteristics of the new electromagnetic shielding materials are investigated. The shielding and reflection principle of the new materials are carried out. The electromagnetic shielding tent which is made of such multilayer composite electromagnetic shielding materials are applied in the integrated lightning protection of information systems, which shows such materials are safe, convenient, practical and worthy of widely application.
