We deduce in this paper the exact solutions for calculation of full width at half maximum (FWHM) and finesse F ring resonators which light is coupled from a bus to ring. These are shown be simple math. Furthermore, we electric field relationships case if generated within out-coupled obtain expression calculations FWHM configuration. Our method produce more accurate results than those with widel...

Imaging with a layered superlens is a spatial filtering operation characterized by the point spread function (PSF). We show that in the same optical system the image of a narrow subwavelength Gaussian incident field may be surprisingly dissimilar to the PSF, and the width of the PSF is not a straightforward measure of the resolution. The FWHM or standard deviation of the PSF gives ambiguous inf...

A four-stage parallel-plate gas insulated Blumlein pulser is under construction. This 90-ohm 16-ns (FWHM) pulser, targeted for operation a~ 400 kV, will be switched by an array of photoconductors triggered by a 15-J, Nd:glass laser for a 1-to-2-ns rise time. A smaller single-stage 100-kV 60-ohm 14-ns (FWHM) pulser, which has been used as a proof-of-principle testbed for the photoconductive swit...

Some numbers that are given on page 15771 do not correspond to the velocity distributions shown in Fig. 4. In the third paragraph of this page it should read ‘‘The distribution has a width (FWHM) of 4.8 m s 1 and 1.4 m s 1 in the longitudinal and transverse direction, respectively. The velocity distribution can also be expressed as a speed ratio of S = 235 (or a temperature of T = 15.0 mK) and ...

The study investigates the growth by pulsed-laser deposition (PLD) of ZnO thin films for the eventual incorporation into piezo-electric actuators and other sensors being developed at the University of Twente. All films are purely c-axis oriented, and results are presented which suggest the production of some of the highest quality ZnO thin films yet reported. These include films with rocking cu...

We report emission from a bismuth doped chalcogenide glass which is flattened, has a full width at half maximum (FWHM) of 600 nm, peaks at 1300 nm and covers the entire telecommunications window. At cryogenic temperatures the FWHM reaches 850 nm. The quantum efficiency and lifetime were as high as 32% and 175 mus, respectively. We also report two new bismuth emission bands at 2000 and 2600 nm. ...

This paper presents a new explanation of the width gamma-ray spectra based on Rahm's electronegativity scale. quantitatively proves, for first time, that positrophilic electrons in positron-electron annihilation process are exactly valence electrons. suggests replacement Full Width at Half Maximum (FWHM) with newly defined physical quantity Average Doppler Shift (ADS). Both FWHM and ADS light e...

Thick films of aligned single wall carbon nanotubes and ropes have been produced by filtration/ deposition from suspension in strong magnetic fields. We measured mosaic distributions of rope orientations in the film plane, for samples of different thicknesses. For an ;1 mm film the full width at half maximum ~FWHM! derived from electron diffraction is 25° – 28°. The FWHM of a thicker film (;7 m...

We propose to use ultrashort laser pulses to detach intact graphene monolayers from a graphite surface, one at a time. As suggested by a combination of real-time ab initio time-dependent density functional calculations for electrons with molecular dynamics simulations for ions, this athermal exfoliation process follows exposure to femtosecond laser pulses with a wavelength of 800 nm and the ful...
