Abstract
In an embodiment, a magneto-dielectric material comprises a polymer matrix; a plurality of hexaferrite microfibers; wherein the magneto-dielectric material has a permeability of 2.5 to 7, or 2.5 to 5 in an x-direction parallel to a broad surface of the magneto-dielectric material and a magnetic loss tangent of less than or equal to 0.03; as determined at 1 GHz, or 1 to 2 GHz.
