PURPOSE:To eliminate influence upon lighting, etc., although a radio wave of ultrahigh frequency is reflected, by opposing glass plates to each other and filling the gap between the glass plates with liquid which reflects a radio wave while allowing visible light to pass through it. CONSTITUTION:In a figure, 1 and 2 are the glass plates, 3 is the liquid filling the gap between the glass plates 1 and 2, and 4 and 5 are spacers; and 6 and 7 are fixed frames, and 8 is an elastic cap made of an elastic material such as rubber, etc., for absorbing the expansion and contraction of the liquid 3. Although the glass plates allow visible light and a radio wave of ultrahigh frequency to pass through them, the liquid 3 such as water reflects the radio wave of ultrahigh frequency while allowing the visible light to pass through it. Thus, the gap between the glass plates 1 and 2 is filled with the liquid 3 such as water to transmit the visible light while reflecting the radio wave of ultrahigh frequency. |
