摘要： A magnetic shielding material includes a material comprising manganese bismuth (MnBi) and tungsten (W), where a ratio of MnBi:W is in a range of 50:50 to about 70:30. A radiation shielding product includes a part including manganese bismuth (MnBi) and tungsten (W), and a plurality of layers having a defined thickness in a z-direction, wherein each layer extends along an x-y plane perpendicular to the z-direction. At least some of the plurality of layers form a functional gradient in the z-direction and/or along the x-y plane, and the functional gradient is defined by a first layer comprising a ratio of MnBi:W being less than 100:0 and an nth layer above the first layer comprising a ratio of MnBi:W greater than 0:100.

摘要： An electrically conductive material configured having at least one opening of various unlimited geometries extending through its thickness is provided. The opening is designed to modify eddy currents that form within the surface of the material from interaction with magnetic fields that allow for wireless energy transfer therethrough. The opening may be configured as a cut-out, a slit or combination thereof that extends through the thickness of the electrically conductive material. The electrically conductive material is configured with the cut-out and/or slit pattern positioned adjacent to an antenna configured to receive or transmit electrical energy wirelessly through near-field magnetic coupling (NFMC). A magnetic field shielding material, such as a ferrite, may also be positioned adjacent to the antenna. Such magnetic shielding materials may be used to strategically block eddy currents from electrical components and circuitry located within a device.
