High frequency permeability of thin film magnetic core.

High Frequency Thin Film Acoustic Ferroelectric Resonators

Both ZnO and PZT Thin Film Bulk Acoustic Resonator filters were fabricated, tested and modeled in this study. The development of an accurate Mason model allows the effect of particular parasitic components on the microwave s-parameters in the region of the series and parallel resonances to be identified. The parasitic components that limit the performance of our ZnO and PbZr0.3Ti0.7O3 Thin Film...

Thin Film Resonators and High Frequency Filters

This paper presents a review of the thin film resonator technology as it relates to wireless and other RF instrumentation. Included in the discussion are emerging aspects of wireless systems and the mutual impact of miniature filters and resonators. Enabling aspects of the thin film resonator (TFR) technology will be described as applied to RF systems. Specific examples of resonators and filter...

Magnetic Thin Film Characterization

An improvement on the fabrication of magnetic thin films is currently on a level of intense research as these films are of great interest in the device industry. Some of these thin films posses high permeability and ferromagnetic resonance (FMR) frequency in the GHz range which are suitable for electromagnetic use. Methods for fabricating these films include sputtering, pulse laser deposition (...
