Permeability and EMI Characteristics of Sendust-Polymer Composite.

Ni-Zn ferrite films synthesized from aqueous solution usable for sheet-type conducted noise suppressors in GHz range

“…The electromagnetic interference (EMI) is a crucial problem for facilitating stable operation of the most advanced and downsized personal computers and cellular phones working at frequency higher than 1 GHz [1]. The noises in GHz range cannot be suppressed efficiently by lumped constant circuits using coils and capacitors.…”

High resistive ferrite films by a solution process for electromagnetic compatible (EMC) devices

“…Composite sheet-type noise suppressors of 0.1-5 mm thickness are widely used as conducted noise suppressors to absorb the electromagnetic noise waves and to avoid crosstalking between the electronic components [3][4][5].…”

Coupling of MnZn-ferrite films onto electronic components by a novel solution process for high frequency applications

“…Conducting noise suppressors are widely used in these highly advanced electronic devices to suppress the emanating electromagnetic noise waves and to avoid cross-talking between devices. [7][8][9][10] These suppressors are magnetic materials that, when placed in the near field of a noise source, absorb the energy of unwanted high frequency noise and convert it into negligible heat (noise currents are dissipated due to the magnetic and/or resistive losses of the materials). The composite-type noise suppressors available in the market are mainly made up of magnetic flakes embedded in a polymer matrix and they are generally of 0.1 to 5 mm in thickness.…”
