The resulting wave displays a wave packet (or beat) that varies along with the so-called group velocity
(v = [v.
Perhaps by listening to the crashing of the water, he developed an idea for translating an oceanographic concept about the group velocity
of waves into an atmospheric concept.
In this paper, optical fiber is designed with tapered core and a metamaterial cladding, which could be used reduce the group velocity
of the fiber to the greater extend when compared to the fiber with no tapering fiber.
The Rayleigh-wave group velocity
for the trace of each event registered has been measured by means of the combination of digital filtering techniques: Multiple Filter Technique (Dziewonski et al.
The results focused on waveforms, fast Fourier transforms (FFT), and frequency/time analysis (with superimposed group velocity
curves) of the signals.
It is used to define the following dimensionless scaled variables in the frame of reference moving with the group velocity
such a tool must have, in addition, a second pulsed laser beam at high average power and fixed wavelength greater than 1 000 nm and a module for the dispersion compensation of the group velocity
Six topics of interest are chosen: narrow band gap semiconductors, including structural properties, crystal growth, optical and electrical properties, and applications; analysis of metamaterial systems and hyperinterfaces with a group velocity
model, including the investigation of such phenomena as optical cloaking; light propagation at metal surfaces; photo-induced spin in materials with varying magnetic properties; the photoelectric effect in perovskite oxide heterostructures; and magnetic resonance effects in large metamolecules.
Washington, August 14 ( ANI ): Researchers from France and China have managed to throttle the group velocity
of light back to less than one billionth of its top speed.
5] have shown that the group velocity
of the asymmetric surface plasmons mode can be negative by engineering the dispersion curve.
ALL signs point to Mexico for pothole-fixing group Velocity
after the firm sealed a five-year deal worth PS7.
In previous articles ,  the method for measurement of the group velocity
of guided waves based on the application of the spectrum decomposition technique was presented.
