ABSTRACT:
A wideband wave absorber of the present invention comprising a sintered magnetic tile and a mat fiber assembly comprising ferrite powder adhered directly or indirectly to the fibers therein, said magnetic powder being adhered to the mat fiber assembly by the step of (a) coating a paint composed of the magnetic powder and a latex, (b) thermally spraying the magnetic powder over the mat fiber assembly, or (c) dusting the magnetic powder on the fibers in the assembly having an adhesive layer formed on their surfaces and covering said powder with an adhesive layer, wherein said mat fiber assembly desirably has a density transition effectuated from the top surface to the inside with increasing density, or has a constant density in its entirety and comprises increasing amounts of adhered magnetic powder from the top surface toward the rear side. According to the present invention, a wave absorber can be made very thin and capable of absorbing waves over a wide range of frequencies. The thin wave absorber results in reduction of cost and can be suitably used in anechoic chambers without occupying much space.
