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].
Choice of an apodization function form is most often determined by specific tasks of application, such as the achievement of the lowest level of the first side lobe of reflection (transmission) band (Figure 4(a), line 3), or the maximum suppression of peaks in the interval between adjacent Bragg reflection bands (Figure 4(a), line 2).
Further let examine transmitted packets of different duration and extent for periodic and quasiperiodic Bragg reflectors at normal incidence with the center frequency of a spectrum near the edge of the Bragg reflection band with value of f/[f.
In the Bragg reflection band for periodic Bragg reflector at the normal incidence transmitted wave packet has the value of CMD that corresponds exceeding the speed of light velocity propagation.
The wave packet widening takes maximum value at the edges of the Bragg reflection frequency band (Figure 6(b), line 1).
Properly speaking, the linear variation of Bragg structure leads to destroying of Bragg reflection.
1 [phi]s then in the case of Bragg reflection with b = [[gamma].
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.
16 corresponding to Bragg reflections from (111), (200) and (311) cubic planes of Ag are observed and compared with COD (Crystallography Open Database), silver file No.
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.
