ELECTROMAGNETIC PULSE PROTECTION DEVICE HAVING CYLINDRICAL STRUCTURE

An electromagnetic pulse protection device having a cylindrical structure. The device (1) consists of multiple stacked annular protection layers (10), wherein each of the annular protection layers (10) is provided with multiple circular tracks arranged from an inner side to an outer side, and each of the circular tracks is provided with multiple sequentially arranged protection units (100). The device of the present invention can fully reflect, absorb, or attenuate electromagnetic pulses, such that a protected object is not influenced by the electromagnetic pulses, thus effectively preventing electromagnetic pulse damage on an electronic information system, and increasing a service life of the electronic information system.
