Electromagnetic wave propagation control member, electromagnetic wave propagation control structure, sash with electromagnetic wave propagation control member and window structure

摘要

The electromagnetic wave propagation control member (5) is arranged at the edge of the opening through which the electromagnetic wave passes and has a groove defined by a conductor. The depth of this groove in the direction perpendicular to the surface of the opening is (λ / √εr) (1/8 +) when the wavelength of the electromagnetic wave is λ, the relative permittivity in the groove is εr, and the positive integer is N. N / 2) or more and (λ / √εr) (3/8 + N / 2) or less. When communicating or broadcasting is received through an electromagnetic wave opening such as a window of a house or a building, an electromagnetic wave propagation control member that controls the propagation of the electromagnetic wave at the opening, a sash and a window structure provided with the electromagnetic wave propagation control member are obtained.
