Brillouin light scattering anisotropy microscopy for imaging the viscoelastic anisotropy in living cells

Nature Photonics
Maintaining and modulating mechanical anisotropy is essential for biological processes. However, how this is achieved at the microscopic scale in living soft matter is not always clear. Although Brillouin light scattering (BLS) spectroscopy can probe the mechanical properties of materials, spatiotemporal mapping of mechanical anisotropies in living ...

Magnetochiral Anisotropy in Bragg Scattering

Physical Review Letters, 2003
We show experimentally that light scattering in cholesteric liquid crystals shows strongly resonant magnetochiral anisotropy near the Bragg resonance; the optical transmission of unpolarized light depends linearly on an external longitudinal magnetic field and on the handedness of the medium.

Radial Anisotropy in Spheroidal Scatterers

IEEE Transactions on Antennas and Propagation, 2015
This paper discusses a spheroidal scatterer in a uniform, static electric field. The scatterer is assumed to be anisotropic and inhomogeneous in a way that relates to the spheroidal coordinate systems, that come in two varieties. The study expands on former research conducted upon radially anisotropic (RA) spheres.

Tetrahedral anisotropy of x-ray anomalous scattering

Physical Review B, 1994
Diffraction of synchrotron radiation in crystals of potassium chromate and germanium reveals a tetrahedral anisotropy of anomalous (resonant) scattering with respect to polarization and wave vectors that introduces a third-rank tensor into the intensity equations.

Ultrasound Scattering Anisotropy Visualization With Ultrasound Tomography

IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2017
An ultrasound tomography (UST) system was used to image ultrasound scattering anisotropy in phantom experiments. This anisotropy was visualized as vector fields with arrows corresponding to the principal scattering angle of each pixel. UST with a ring-array system allows for a large range of transmit and receive angle combinations, producing real-time ...

The anisotropy of thermal diffuse scattering

Acta Crystallographica Section A, 1972
In order to correct X-ray integrated intensities for thermal diffuse 1-phonon scattering, the influence of the anisotropy of the lattice vibrations was examined. Using an oscillating-crystal technique with a long slit between source and goniometer, it is shown that the anisotropy of the three-dimensional intensity function of the 1-phonon scattering is
