ABSTRACT:
A broad-band radio wave absorber is disclosed which includes a radio wave reflecting surface, and a plurality of magnetic members provided on the reflecting surface and arranged in columns and rows in the directions of X- and Y-axes, each of the magnetic members having a first section extending in parallel with the Y-axis and a second section in contact with the first section throughout the height thereof and extending in parallel with the X-axis, such that the first sections in each column and the second sections in each row are spaced apart from each other at a predetermined distance. Each of the first and second sections has a part having a length which is smaller than the distance at which each adjacent two sections are spaced apart, so that there is formed an aperture between each of the two adjacent sections.
