The electromagnetic absorption in the near- and the far-field regime for the soft magnetic metal-polymer composite films was greatly dependent on the film density. The electromagnetic absorption in the RF range significantly increased with increasing film density, which was caused by the increase of the magnetic permeability and the electrical conductivity. As a result, the high-density soft magnetic film showed excellent electromagnetic absorption for the near- and the far-field electromagnetic shielding and was applicable as an electromagnetic absorber for high-frequency devices operated over 0.1 GHz.
