| titleOfInvention | Radio wave absorption panel |
| abstract | (57) [Summary] [Problem] Although the adoption of a radio wave absorption wall in a high-rise building as a measure against TV radio ghost is becoming common, most of the measures mainly deal with the VHF band, and a wide band shared with the UHF band. No radio wave absorption band can be seen. SOLUTION: The second layer has a first layer made of a calcium silicate plate, a second layer made of a ferrite plate, a third layer made of a calcium silicate plate, and a fourth layer made of a metal reflector. The layer is a ferrite plate having a width (A) of 10 mm to 25 mm, a thickness (B) of 4 to 12 mm, and a length (C) of 200 mm or more. The gap of the ferrite plate is set to 45% to 55% in the electric field direction orthogonal to the magnetic field direction. A radio wave absorption panel, which is an absorber layer formed by repeating the above. |
