Abstract (en)
[origin: EP0828313A2] An electromagnetic-wave absorber (1) which can efficiently absorb the electromagnetic wave over broad band, with a reduced thickness and weight, which is superior in workability for attachment comprising a first ferrite sheet (3) of the predetermined thickness attached with a metal plate (15) for reflecting electromagnetic-wave on the back thereof, a second ferrite sheet (5) which has the thickness thinner than that of said first ferrite sheet (3) and is located in the front of said first ferrite sheet (3) and a dielectric means (7) which has the predetermined thickness and is located between said first and second ferrite sheets (3,5). <IMAGE>
