ELECTROMAGNETICALLY SHIELDED BUILDING

摘要

All or a portion of the periphery of a building is constituted by an electromagnetic shielding structure to form an electromagnetically shielded space within the building. This is done by constructing the body of the building of ferrite- or mesh-containing concrete, or by constructing the external wall of the building of PC panels containing an imbedded mesh or of curtain walls consisting of an electromagnetic shielding material and fixed to the body of the building by anchor bolts through the intermediary of metal fasteners. Sets of communications equipment within the building communicate with one another by way of electric waves. Since the space within the building is electromagnetically shielded from the outside, any desired electric wave frequency band can be selected for the communication of information among the sets of communications equipment.
