  • ELECTROMAGNETIC RADIATION ABSORBER AND METHOD FOR ABSORBING ELECTROMAGNETIC RADIATION
    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.
