  • Publication number: 20080084259
    Abstract: A thin, light and soft electromagnetic wave absorber is disclosed exhibiting an excellent workability. The first conductor element group of a first conductor element layer consists of aligned cross conductor elements and square conductor elements in regions surrounded by cross conductor elements. A radio wave incident from the first conductor element layer side is received by each element, internally subjected to multiple reflection and then absorbed by a first loss material layer. Since the first conductor element group is realized by the cross conductor elements and the square conductor elements, receiving effect is enhanced and the radio wave can be collected with a high collection efficiency.

  • Publication number: 20070252771
    Abstract: An electromagnetic interference suppressor of substantially unpressurized sheet form is obtained by applying and drying a magnetic paint, and comprises 30 to 80% by volume of soft magnetic powder and 20 to 70% by volume of a binder. The binder is an elastomer or a resin that a glass transition point and/or a softening point is 50° C. or more and a storage modulus (E?) is 107 Pa (JIS K 7244-1) or more in a state containing neither solvent nor filler at room temperature. This electromagnetic interference suppressor exerts a superior electromagnetic interference suppressing effect.
