       The present invention relates to a vent for electromagnetic protection of information security and a strong pulse, and more particularly, to prevent the tapping by the electromagnetic wave due to the natural electromagnetic emission, and to the strong electromagnetic pulse generated by the explosion of a nuclear bomb or an electronic bomb. The present invention relates to a ventilation opening having a shielding function for preventing disturbance and failure of an electronic device.

       In general, electromagnetic waves refer to wavelengths generated by interaction between electricity and magnetism, and are naturally occurring in all electromagnetic products such as electric household appliances around us and various information and communication devices.

       The electromagnetic waves are harmful and harmless to the human body according to their strength, and technologies for blocking them and absorbing technologies are continuously being researched and developed, while detecting and analyzing them, and using them as various information. Sometimes.

       The eavesdropping by natural electromagnetic waves began to be recognized by information agencies in the 1950s, and in the United States, the term TEMPEST is used as a plan code name to be free from the eavesdropping by the electromagnetic waves. It means the detailed standard of safety from radiation dose and eavesdropping, and it is known as the concept of wireless eavesdropping prevention technology, eavesdropping, eavesdropping defense technology including the concept of information leakage prevention measures, the technology of getting information and eavesdropping from the other party.

       Therefore, as users who use electromagnetic wave generation devices such as wired and wireless voice and video, we are in an urgent reality to prevent personal, corporate, public organizations, infrastructure, and national information from being leaked and used by the other party.

       In addition, an electromagnetic pulse (EMP) refers to a large energy generated naturally or artificially, the natural 'EMP' may be a lightning strike, and an artificial 'EMP' may be generated during an explosion of a nuclear bomb or an electronic bomb. Strong pulses of energy.

       As such, the electronic devices exposed to the 'EMP' may be severely damaged due to the impact of a large energy pulse, leading to malfunctions or breakages. It is an urgent reality to seek measures to protect against.
