Electromagnetic Shielding Design of Transfer Orifice for Military Shelter

Modern warfare has put forward higher and higher electromagnetic shielding requirements for the shelters loaded with various types of high-performance electronic equipment. The use of high-performance electromagnetic shielding shelters has become an important means to ensure the combat effectiveness and survivability of weapons and equipment. In view of the design of the transfer aperture of a certain type of military shielded shelter, starting from the electromagnetic shielding principle of the shelter, according to the theoretical calculation method of electromagnetic shielding effectiveness, the structural design elements of the shielded shelter transit orifice are detailed. Finally, according to the national military standard for shielding test verification, the shelter transfer orifice can meet the requirements of the shielding index, which can provide reference for the similar shielded shelter design.
