ABSTRACT:
An electromagnetic wave absorber includes a metal plate capable of reflecting electromagnetic waves and adapted to be fitted onto a fixed object. A first sintered ferrite plate is disposed in front of the metal plate, and has a thickness of between 3 and 5 mm. A dielectric member is disposed in front of the first sintered plate, and has a low dielectric constant and a thickness between 10 and 30 mm. And a second sintered ferrite plate is disposed in front of the dielectric member, and has a thickness of between 1 and 2 mm.
