Regulations of the Peoples Republic of China on the safety control of computer information systems Brief introduction of electromagnetic shielding room Computer, communication machine and electronic equipment will produce electromagnetic wave of certain intensity when they are working normally. The electromagnetic wave may interfere with other equipment or be received by special equipment to steal its work content. At the same time, these electronic equipment also needs to guarantee its normal work under the electromagnetic environment of less than a certain intensity. Shielding is the use of metal plates (metal mesh) made of hexahedron, the electromagnetic wave is limited to a certain range of space, so that its field energy from one side to the oth
