Wave absorbing wall

Abstract

Abstract PURPOSE: To enable wave absorbing function to cover a range of both VHF and UHF, by laying a first ferritic molding for absorbing waves of VHF frequency band on a second ferritic molding for absorbing waves of UHF frequency band. CONSTITUTION: Exterior tiles 1 of electric wave transmitting material are used for an exterior wall of a building and spreaded on the most outermost layer of a wall. In the inside of this exterior tile 1, a first ferritic molding 2 which has a function to absorb waves of VHF frequency band is fixed. And, in the inside of the first ferritic molding 2, a second ferritic molding 4 which a function to absorb a waves of UHF frequency band is fixed through a first wave reflecting plane 3 of a metallic mash. Further, in the inside of the second ferritic molding 4, a second wave reflecting plate 5 of a metallic mesh is provided. Therefore, since the waves of VHF and UHF frequency bands are respectively reflected by the first and second wave reflecting plates, the waves repeat incidence and reflection thereof between respective ferritic moldings, and thereby the waves can be effectively absorbed by the ferritic molding.
