Title:
REFLECTING PANEL, ELECTROMAGNETIC WAVE REFLECTING DEVICE USING SAME, ELECTROMAGNETIC WAVE REFLECTING FENCE, AND PRODUCTION METHOD FOR REFLECTING PANEL
Document Type and Number:
WIPO Patent Application WO/2024/070407
Kind Code:
A1
Abstract:
Provided is a reflecting panel in which at least one of reflection efficiency and reflection direction accuracy is improved. The reflecting panel comprises a first substrate, a second substrate, and an intermediate layer that is provided between the first substrate and the second substrate and is obtained by laminating a first intermediate film, a second intermediate film, and a third intermediate film in the stated order. An interface between the first intermediate film and the second intermediate film, or an interface between the second intermediate film and the third intermediate film is a reflecting surface that reflects electromagnetic waves of 1-300 GHz. When the average thickness of the first intermediate film is d1, and the average thickness of the third intermediate film is d2, the reflecting panel satisfies the expression 0.5 < d1/d2 < 1.5.
