Bragg scattering

Bragg scattering

[′brag ‚skad·ər·iŋ]
(solid-state physics)
Scattering of x-rays or neutrons by the regularly spaced atoms in a crystal, for which constructive interference occurs only at definite angles called Bragg angles. Also known as Bragg diffraction; Bragg reflection.

Practically, these time series are induced by backscatter from the sea due to the first-order Bragg scattering. In this study, we investigated three radial current scenarios in this range cell: a uniform current flowing parallel to shore (which is a representation of single DOA for any current velocity), a parabola-shaped current (which involves dual DOAs for some current velocity), and a current jet superimposed with a uniform parallel-to-shore current (which implies three DOAs for some current velocity).
The first order solution can be interpreted as a Bragg scattering modulation from incident direction to arbitrary direction determined by [k.sub.x].
Interference of the Bragg scattering is considered as a cause of these phenomena, the so-called Bragg gap.

The graphite element is mounted on a perfect Si single crystal 1 mm thick to minimize any phonon scattering, while the highly perfect extinction-limited crystal essentially eliminates Bragg scattering from the mount.

With SDFM considering Bragg scattering from capillary waves, sea surface can be meshed into larger triangle patches, which adapt well to SBR method for ray tracing between the ship and ocean.
As for the case for cross-polarization (HV-pol), the curves present a similar variation trend throughout the whole angles for both deep sea and shallow sea situations: NRCSs decrease with increasing wind fetches, which may imply that the mechanism of Bragg scattering rather than the nonlinear interaction dominates the variation of NRCSs with incident angle for the cross-polarization case.
To date, the Bragg scattering (scattering of linear waves) has been well studied in many papers [1-3].
Short wavelength neutrons can be filtered from the beam using Bragg scattering from polycrystalline materials, the most common being beryllium.
