ABSTRACT:
A broad-band radio wave absorber including a radio wave reflecting surface, and a plurality of magnetic members provided on the reflecting surface and arranged in columns and rows, each of the magnetic members being composed of a first layer in the form of a square tile or a cross and a second layer superimposed on the first layer and having at least one cylindrical block having a diameter smaller than the width of the first layer. The first layers of adjacent two magnetic members are in contact with each other. When the second layer has a plurality of cylindrical blocks, they are coaxially superimposed in turn in a step wise manner.
