    摘要: A film structure for absorbing electromagnetic wave and manufacturing method thereof is provided. The multilayer film structure is composed of a plurality of polymer films (100) and a plurality of permeability films (104). The polymer films (100) have a multi-film stacking structure and the polymer films are composed of a carbon group compound structure (102). The permeability films are formed on each surface of the polymer films. Thus, every neighboring permeability films will have magnetic moments in opposite direction, and all the emitted electromagnetic waves will be cancelled by the permeability films, or be reflected in any one of the polymer films until the energies of the electromagnetic waves are consumed, or be absorbed by the carbon group compound structure and be transferred into thermal energy.

    摘要: A conductive pattern (12) basically has a substantially polygonal outline shape which is a polygon and can have a high peak value of the electromagnetic wave absorption amount as compared to a case when the conductive pattern has a circular outline shape. Thus, the conductive pattern is basically a polygon and at least one corner portion is shaped in curve. This minimizes the shift of the frequency at which the absorption amount becomes a peak value by the polarization direction of the electromagnetic wave. Accordingly, it is possible to realize an electromagnetic absorber having an excellent electromagnetic wave absorption characteristic exhibiting a high peak value of the absorption amount of the electromagnetic wave and a small shift of frequency at which the absorption amount becomes a peak value by the polarization direction of the electromagnetic wave.

    摘要: A silicone gel sheet is heat-molded from a silicone gel composition comprising metal oxide magnetic particles and a thermoconductive filler. The sheet has a high electromagnetic wave absorbing property at a frequency ranging from 500 to 800MHz. The hardness of the composition after hardening treatment is set in the range of 10-95 when measured with an ASKER F-type hardness meter. The metal oxide magnetic particles used here can be either Mn-Zn ferrite or Ni-Zn ferrite whose average particle diameter is 1-50 µm. For the thermoconductive filler, a metal oxide, aluminum nitride, boron nitride, silicon nitride, or silicon carbide can be used. In the silicone gel molded sheet (1), an electroconductive mesh (3) is embedded in one surface layer of the silicone gel layers (2) while the other surface (4) is provided with adhesiveness. As a result, an electromagnetic wave absorbing thermoconductive silicone gel molded sheet is provided at a low cost, and the sheet is superior both in electromagnetic wave absorbing property and thermoconductivity.
