RADIO WAVE ABSORBING WALL

PROBLEM TO BE SOLVED: To provide a radio-wave absorbing characteristics and weather- resistance which is equal to or better than normal as well as high strength for, especially, good workability by setting a distance between a ferrite tile and a reflector to a specific value or less. SOLUTION: With an interval equal to 10% or longer than the length of a ferrite tile 1 in magnetic-field component direction, the ferrite tile 1 is provided in the magnetic-field component direction. With less than 10%, a required radio-wave absorption characteristics is not provided at high frequency. In addition, each ferrite tile 1 is attached with a reflection foil body 5 of metal thin plate and foil, on its indoor side, as a radio-wave reflector, in such way as with no interruption in electric-wave direction. When a reflection bar is employed as a reflector, with the use of stainless steel bar or reinforcing-bar processed for lust-proof, it is provided near the ferrite tile 1, within 15 mm from it. Thus, a radio-wave absorbing wall of weather-resistance, workability, and strength which are equal to or better than normal is obtained.
