  • Patent number: 10932399
    Abstract: Examples include a method of forming an electromagnetic shielding material, the method including: applying a magnetic field to a precursor material that includes first ferromagnetic particles embedded within a first portion of a matrix material and second ferromagnetic particles embedded within a second portion of the matrix material, thereby causing the first ferromagnetic particles and the second ferromagnetic particles to move such that longitudinal axes of the first ferromagnetic particles and the second ferromagnetic particles become more aligned with the magnetic field; thereafter forcing the first portion of the matrix material through a filter, thereby moving the first ferromagnetic particles from the first portion of the matrix material into the second portion of the matrix material; and curing the second portion of the matrix material to form the electromagnetic shielding material.

  • Patent number: 10856455
    Abstract: Electromagnetic interference (EMI) shielding panels and associated methods. An EMI shielding panel includes a binding matrix material and electrically conductive elements distributed throughout the binding matrix material. The electrically conductive elements are aligned such that conductive element longitudinal axes of the electrically conductive elements are at least substantially parallel to a shielding axis of the EMI shielding panel. The electrically conductive elements are configured to at least partially attenuate an incident electromagnetic wave that is incident upon the EMI shielding panel. A method of forming an EMI shielding panel includes providing a shielding mixture that includes electrically conductive elements distributed throughout an uncured binding matrix material, magnetically aligning the electrically conductive elements, and curing the binding matrix material to form the EMI shielding panel.
