We explore the frequency dependent permittivity of Ruddlesden-Popper series Sr(n+1)Ti(n)O(3n+1) (n= 1, 2, 3) thin films as a function of temperature and dc electric-field. Interdigitated capacitors and coplanar waveguides are used to extract the frequency

Third order Intermodulation Distortion in Film Bulk Acoustic Resonators at Resonance and Antiresonance

Eduard Rocas, Juan C. Collado Gomez, Jordi Mateu, Nathan D. Orloff, Alberto Padilla, Juan Callaghan, James C. Booth, Robert Aigner
This paper presents recent measurements and modeling of the third order intermodulation products of a Film Bulk Acoustic Resonator (FBAR), for a various values of frequency spacing between driving tones. The frequency dependence of voltage and current in

Broadband Permittivity Measurements of Thin-Film Ferroelectrics to 40 GHz

February 25, 2008

Nathan D. Orloff, James C. Booth, Makoto Murakami, Ichiro Takeuchi
We demonstrate a novel experimental technique to measure the complex permittivity function of dielectric thin films over the frequency range from 100 Hz to 40 GHz. We apply this technique to determine the broadband permittivity function for ferroelectric

Microwave Dielectric Heating of Fluids in an Integrated Microfluidic Device

October 3, 2007

Jayna J. Shah, Siddarth Sundaresan, Jon Geist, Darwin Reyes-Hernandez, James Booth, Rao Mulpuri, Michael Gaitan
Rapid, selective, and uniform heating of sub-microliter size fluid volumes is vital for micro total analysis system (?gTAS) applications. In this work, we present an approach to localized and selective heating of fluids in a microfluidic network. This is

Broadband Characterization of Multilayer Dielectric Thin-Films

June 3, 2007
Author(s)
Nathan D. Orloff, Jordi Mateu, Makoto Murakami, Ichiro Takeuchi, James C. Booth
We develop a measurement technique for obtaining the broadband complex permittivity of thin-film dielectric materials over the frequency range from 100 Hz-40 GHz. Such broad frequency coverage can only be accomplishe3d by combining lumped-element and

Detuning and Saturation of Superconducting Devices: Formulation and Measurements

June 3, 2007
Author(s)
Carlos Collado, Jordi Mateu, James Booth, J M. Callaghan
Saturation and detuning of High Temperture Superconducting (HTS) resonators and filters may occur due to the inherent nonlinear properties of the superconductor. In HTS transmission lines, these nonlinear properties introduce a dependence of the inductance

Disorder effects on the intrinsic nonlinear current density in YBa2Cu3O7

June 1, 2007
Author(s)
Brian M. Andersen, James Booth, P.J. Hirschfeld
We present harmonic generation measurements of the intrinsic nonlinear current density j2 of (YBCO) films at temperatures close the Tc. Experiments on a range of different quality samples allow us to extract the dependence of j2 on the penetration depth of
