    Abstract: A magnetic isolator includes a dielectric film having a layer of electrically-conductive soft magnetic material bonded thereto. The layer of electrically-conductive soft magnetic material comprises substantially coplanar electrically-conductive soft magnetic islands separated one from another by gaps. At least some of the electrically-conductive soft magnetic islands have an outer insulating oxidized layer that electrically insulates them from adjacent electrically-conductive soft magnetic islands. The gaps at least partially suppress electrical eddy current induced within the layer of soft magnetic material when in the presence of applied external magnetic field. An electronic device including the magnetic isolator and a method of making the magnetic isolator are also disclosed.

    Abstract: Polymer composites that are suitable for use as electromagnetic interference mitigaters include a lossy polymeric matrix, ceramic particles dispersed within the polymeric matrix, and conductive particles dispersed within the polymeric matrix. The lossy polymeric matrix may be a fluorocarbon-based polymer matrix, or an epoxy-based polymer matrix. The ceramic particles may be metal oxide particles, especially copper oxide (CuO) particles. The conductive particles may be carbon black. Other electromagnetic interference mitigating polymer matrices include a lossy polymeric matrix and copper oxide (CuO) particles dispersed within the polymeric matrix.
