  2. Bragg's law - Wikipedia

    en.wikipedia.org/wiki/Bragg's_law

    This equation, Bragg's law, describes the condition on θ for constructive interference. [12] A map of the intensities of the scattered waves as a function of their angle is called a diffraction pattern. Strong intensities known as Bragg peaks are obtained in the diffraction pattern when the scattering angles satisfy Bragg condition.

  3. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    Scattering also includes the interaction of billiard balls on a table, the Rutherford scattering (or angle change) of alpha particles by gold nuclei, the Bragg scattering (or diffraction) of electrons and X-rays by a cluster of atoms, and the inelastic scattering of a fission fragment as it traverses a thin foil.

  4. Dynamical theory of diffraction - Wikipedia

    en.wikipedia.org/wiki/Dynamical_theory_of...

    The dynamical theory of diffraction considers the wave field in the periodic potential of the crystal and takes into account all multiple scattering effects. Unlike the kinematic theory of diffraction which describes the approximate position of Bragg or Laue diffraction peaks in reciprocal space , dynamical theory corrects for refraction, shape ...

    The Australian Centre for Neutron Scattering (ACNS), formerly the Bragg Institute, is a landmark neutron and X-ray scattering facility in Australia. It is located at the Australian Nuclear Science and Technology Organisation 's ( ANSTO ) Lucas Heights site, 40 km south-west of Sydney , in New South Wales , Australia.

    The following year, the important Battle of Điện Biên Phủ was fought between the Việt Minh (led by General Võ Nguyên Giáp), and the French Union (led by General Henri Navarre, successor to General Raoul Salan). The siege of the French garrison lasted fifty-seven days, from 17:30, 13 March to 17:30, 7 May 1954.

  7. Distributed Bragg reflector - Wikipedia

    en.wikipedia.org/wiki/Distributed_Bragg_reflector

    Time-resolved simulation of a pulse reflecting from a Bragg mirror. A distributed Bragg reflector (DBR) is a reflector used in waveguides, such as optical fibers.It is a structure formed from multiple layers of alternating materials with different refractive index, or by periodic variation of some characteristic (such as height) of a dielectric waveguide, resulting in periodic variation in the ...

  8. Fiber Bragg grating - Wikipedia

    en.wikipedia.org/wiki/Fiber_Bragg_grating

    A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror .

    Ngô Bảo Châu (Vietnamese: [ŋo ɓa᷉ːw cəw], born June 28, 1972) [3] is a Vietnamese-French mathematician at the University of Chicago, best known for proving the fundamental lemma for automorphic forms (proposed by Robert Langlands and Diana Shelstad).
