    Abstract: An electromagnetic wave suppression sheet is provided to obtain high electron wave absorption characteristic with thin sheet thickness by designing a real number unit and an imaginary number unit of the dielectric constant of sheet composition into a predetermined standard. An electromagnetic wave suppression sheet(1) is composed of a magnetic powder(2) and an insulating material(3). The dielectric constant of the component of the electromagnetic wave suppression sheet is set. The real number unit(epsilon') of the dielectric constant(epsilon) of the in-plane direction of the electromagnetic wave suppression sheet is expressed in epsilon '>=200. The imaginary number unit(epsilon") of the dielectric constant is expressed in epsilon ">=25. The real number unit and imaginary number unit of the dielectric constant have anisotropy about the in-plane direction of the electromagnetic wave suppression sheet. The charge density of the magnetic powder is in the range of 2.3(g/cm^3)~3.5(g/cm^3). The content of the magnetic powder is larger than 30 volume % and is smaller than 45 volume %.

    Abstract: Composite materials that include a resin containing a polymer obtained by polymerizing a monomer mixture that contains at least one polymerizable monomer and a magnetic material, where the composite material can be used to make sheet stock and articles, such as storage containers. The composite materials can be made by mechanical milling the magnetic material into the resin or by using bulk, suspension, emulsion, mini-emulsion or micro-emulsion polymerization techniques where the resin is formed in the presence of the magnetic material. Articles made of the composite material can be used in a method of deterring theft of an article which includes providing the above-described container, applying a magnetic field to an interrogation zone, causing movement of the container into the interrogation zone, and detecting a magnetic response resulting from the container moving into the interrogation zone. ® KIPO & WIPO 2008
