The Bragg reflection wavelength ([[lambda].sub.R]) of c-SCPhCs can be calculated according to the Bragg law 17]:
The Bragg reflection light shifted toward a shorter wavelength when the incident angle increased [7-9].
Dependences of the skewness and kurtosis of the reflected wave packet versus carrier frequency in the Bragg reflection band for chirp structures will be calculated.
For packet duration a = 300 in the Bragg reflection band CMD and GD response coincide with greater accuracy (on the Bragg frequency ([DELTA][[tau].sub.g] - [DELTA][[tau].sub.e])/[[sigma].sub.init] [approximately equal to] 0.074), and besides reflected packet has had shorter duration (Figure 3(b), line 3).
Analysis shows that any non-symmetric Bragg reflection and any reflection in the Laue scheme are completely unacceptable for practice because already at small distances L ~10-30 cm the reflected pulse is blurred so much so much that it almost completely disappears (Figs.
(25), for the Bragg reflections observed at 19.56[degrees] and 28.69[degrees] (2[theta]).
XRD results showed peaks corresponding to (111), (200), (220) and (322) Bragg reflections. This pattern showed presence of SNPs in the sample (Figure 4).
There were four diffraction peaks (2-theta) at 38.16, 44.29, 64.30 and 77.91 corresponding to Bragg reflections (111), (200), (202) and (311) cubic planes of Ag are observed and compared with COD (Crystallography Open Database), silver file No.
With this crystallite which has a centre, we have plotted crystallite size (D in nm) for the two Bragg reflections (012) and (321) in Figure 3 which is not drawn to scale.
The two FBGs will be in the same fiber-optic and will provide two different Bragg reflections, one dependent on strain and temperature and the other dependent only on temperature for compensation.
Bonse and Hart [1] proposed multiple Bragg reflections from a channel-cut single crystal to obtain a beam with a nearly rectangular angular profile.
This analyzer crystal was placed in the H-beam of the interferometer and rotated about until both the symmetric and anti-symmetric Bragg reflections were found.
