  • Patent number: 8643531
    Abstract: An electromagnetic wave absorber includes a dielectric layer, a divided conductive film layer and an electromagnetic wave reflective layer, wherein a ratio of thickness ‘d’ and wavelength ‘?’ satisfies a condition of [0.01?d/?0.03], weight per unit area of the electromagnetic wave absorber falls within a range of 1000 g/m2 and 3000 g/m2. The divided conductive film layer is configured such that each side's length of conductive films is dimensioned within a range of 0.5 mm and 4.8 mm and arrangement distance between adjoining conductive films is taken within a range of 0.01 mm and 3 mm.

  • Publication number: 20110147073
    Abstract: An electromagnetic radiation absorber is made up of a composite of base material and filler. The base material is formed of high permittivity dielectric material and formed in a cubic shape. The filler is formed of high magnetic permeability material and fills in long holes formed inside the base material in three directions. In the composite, the high permittivity dielectric material and the high magnetic permeability material are arranged in a three-dimensionally continuous manner. Accordingly, a thinned and light-weighted electromagnetic radiation absorber and a method for absorbing electromagnetic radiation are provided which have a high electromagnetic radiation absorbing property with respect to electromagnetic radiation of wide band including electromagnetic radiation of low frequency.

  • Patent number: 7601281
    Abstract: A flowable insulating resin 1 is placed in a sheet-like molding die space and conductive magnetic particles 2 are dispersed in the insulating resin 1. A first magnetic field G1 is acted in the sheet thickness direction on the position where a conductive path is to be formed in the die space, and conductive magnetic particles 2a are locally collected together to form a conductive path. Simultaneously, a second magnetic field G2 is acted in the sheet thickness direction on the intermediate region and the magnetic field G2 is moved in the lateral direction to move conductive magnetic particles 2b left in the intermediate region to join the collection forming the conductive path. As a result, the number of the conductive magnetic particles left in the insulating resin becomes smaller.
