Abstract: An electromagnetic shield-type doorway for a building is provided with two doors having a curved passageway between them. By lengthening the passageway to such an extent that the two doors cannot be opened simultaneously, electric waves can be blocked at either of the doors. The electromagnetic shielding effect can be enhanced by installing a revolving door in the passageway and attaching electrically conductive brushes to at least the lower edge and one side edge of the revolving door to fill the gaps at these edges. In a system for electromagnetically shielding a building, a doorway passageway of the building is partitioned by three or more doorways each having an electromagnetic shielding function. When persons leaving and exiting a building simultaneously approach entrance and exit doors at the ends of the doorway passageway so that these doors open at the same time, the central doorway remains closed to maintain the integrity of the electromagnetic shield.

Abstract: A building with an electromagnetic shield structure for individual floors uses an electromagnetic shielding material in a body of the building and in openings such as windows and doorways, and the external wall surface of the building is covered with an electromagnetic shielding layer. An electromagnetically shielded space within the building is divided into individual floors by floor partitions using an electromagnetic shielding material. Wireless communication utilizing electric waves is carried out within the building, with the same frequency band or any desired frequency band being allotted to each floor. With the above arrangement, sets of communications equipment using the same frequency band on one floor can communicate with one another without interfering with sets on another floor, even though the sets of equipment on the other floors use the same frequency band.
