Surface-plasmon-enhanced electric fields in two-dimensional arrays of gold nanodisks

August 4, 2008
Author(s)
Ward L. Johnson, Sudook A. Kim, Zhandos Utegulov, B. T. Draine
… approximation, as a function of nanodisk diameter (20 − 50 nm), height (10 − 100 nm), ratio of the array spacing to diameter (1.3−4.7), and angle of incident light. The primary focus is on … height/diameter ratio for maximum intensities is between 0.7 and 1.5 and not strongly dependent on the spacing for a …

Resonance-free Low-pass Filters for the ac Josephson Voltage Standard

March 1, 2006
Author(s)
Michio Watanabe, Paul Dresselhaus, Samuel Benz
We have designed and characterized superconducting integrated circuits for the ac Josephson voltage standard that demonstrate significantly improved performance. The typical circuit consists of an array of superconductor-normal metal-superconductor

Thomas Gerrits, Michael Schneider, Thomas J. Silva
… of ferromagnetic damping for thin Permalloy (Ni 80 Fe 20 ) films grown with Cu capping layers of variable thickness … magnetometer in the frequency range between 2.3 and 2.7 GHz. The damping was enhanced if the Cu layers were thicker …

Improved stabilization of a 1.3 um femtosecond optical frequency comb using spectrally tailored continuum from a nonlinear fiber grating

January 15, 2006
Author(s)
Kyoungsik Kim, Leo W. Hollberg, Scott A. Diddams, P. S. Westbrook, Jeffrey W. Nicholson
We report the significant enhancement ($+$24 dB) of the optical beat note between a 657-nm cw laser and the second-harmonic generation of the tailored continuum at 1314 nm generated with a femtosecond Cr:forsterite laser and a nonlinear fiber Bragg grating

Improved stabilization of a 1.3 um femtosecond optical frequency comb using spectrally-tailored continuum from a nonlinear fiber grating

P J. Disimile, John M. Davis
… The mean streamwise velocity was found to be 6.30 m/s (20.7 ft/s) +/-10% with a nominal turbulent intensity of 5.0 % …

On the Interaction of a Liquid Droplet with a Pool of Hot Cooking Oil

November 1, 2003
Author(s)
Samuel L. Manzello, Jiann C. Yang, Thomas G. Cleary
An experimental study is presented for distilled water droplets impacting on a heated pool of cooking oil. The impaction process was recorded using a high-speed digital camera at 1000 frames per second. The initial droplet diameter was fixed at 3.1+0.1 mm
