    Abstract : Sequential 3D (S3D) integration has been identified as a potential candidate for area efficient ICs. It entails the sequential processing of tiers of devices, one on top the other. READ MORE

  5. 3. Impedance of Soft Magnetic Multilayers : Application to GHz Thin Film Inductors

    Author : Andrey Gromov; KTH; []
    Keywords : inductor; impedance; magnetic; eddy currents; FMR;

    Abstract : A theoretical approach to calculating impedance of metallicmagnetic/conductor layered structures is developed. Thefrequency range considered extends to the ferromagneticresonance region of soft magnetic films (of the order of 1GHz). READ MORE

  6. 4. Design Aspects of Inductive Power Transfer Systems for Electric Vehicle Charging
