Sentence examples for dispersion regions from inspiring English sources

The nonlinear propagation of hyperbolic secant soliton optical pulses with initial first-order phase modulation in the anomalous dispersion regions of optical fibers are investigated numerically.

Due to large Bragg reflection, coupling of the band edge modes at the flat dispersion regions that possess small group velocities is inefficient.

A few peculiar dispersion regions are observed in the ferroelectric phase, which we attribute to the coexistence of ferroelectric and dipolar glass phases.

It can be observed that there is anomalous dispersion regions when 3.5 < E < 4.5 eV and, as well as normal dispersion when 3 < E < 3.5 eV for doped samples.

For example, Ye et al. experimentally demonstrated a metamaterial perfect absorber in which the frequency-independent dispersion regions of both permittivity and permeability are stretched to an ultra-wide band from 0.5 to 2.5 GHz, and the real and imaginary parts of the complex constitutive parameters are precisely tuned to satisfy a modified model of a perfectly matched layer [63].

At the pump wavelength of ∼1750 nm which is in the deep anomalous dispersion region, SC spectrum evolution is mainly due to multiple solitons and dispersive waves (DWs), and three pairs of multiple optical solitons and DWs are observed.

Distinct dispersive peaks may also appear when an optical pulse, launched in the normal dispersion region, later begins to propagate in the anomalous dispersion regime because of its spectral broadening.

In the anomalous dispersion region, there are many peaks indicating the anomalous behavior of refractive index.

In the normal dispersion region, the refractive index dispersion was analyzed using the single model developed by Wemple and DiDomenico.

The crack dispersion region was wider on the outer surface than on the inner surface of G1.

Meanwhile, the smaller band gap in thicker film could cause a redshift of the anomalous dispersion region as illustrated in Fig. 3.
