    • An electromagnetic interference shielding composite is provided. The electromagnetic interference shielding composite comprises: a high permittivity polymer having a permittivity of at least about 5; a plurality of magnetic particles dispersed within the high permittivity polymer; and a plurality of dielectric particles dispersed within the high permittivity polymer. In another embodiment, an article comprising a device susceptible to electromagnetic radiation and a shielding material disposed to shield the device from electromagnetic radiation is provided. The shielding material comprises, a high permittivity polymer; a plurality of magnetic particles dispersed within the high permittivity polymer; and plurality of dielectric particles dispersed within the high permittivity polymer.
