Electric birefringence imaging of electrokinetic agarose orientation.
Time-resolved and steady-state electric birefringence imaging with a slow-scan video camera is used to study orientation during DNA agarose gel electrophoresis. The hydrodynamically induced gel distortion is shown to be the major source of birefringence under electrophoresis running conditions and to generate a birefringence image that approximates the image of the DNA concentration gradient in...
متن کاملDirect measurement of electric-field-induced birefringence in a polymer-stabilized blue-phase liquid crystal composite.
We demonstrate a method to directly measure the electric-field-induced birefringence of a polymer-stabilized blue-phase liquid crystal (PS-BPLC) composite. The induced birefringence follows the extended Kerr effect well and is approximately 3X the ordinary refractive index change. The measured data are validated by comparing the simulated and measured voltage-dependent transmittance with an in-...

متن کاملStructure of microemulsions from magnetic and electric birefringence measurements
2014 Magnetic and electric birefringence experiments have been performed on microemulsions of Na octylbenzene sulfonate (OBS)-pentanol-decane-water (with 0.3 % NaCl), in the homogeneous liquid region of the pseudo-ternary diagram. The Cotton-Mouton constant is related qualitatively to the structure of the microemulsion. It is discussed in terms of magnetic orientation of anisotropic rigid objec...
متن کاملThe Double Jones Birefringence in Magneto-electric Medium
In this paper, the Maxwell's equations for a tensorial magneto-electric (ME) medium are solved, which is an extension to the work on the uniaxial anisotropic nonmagnetic medium. The coefficients of the dielectric permittivity, magnetic permeability, and of the magneto-electric effect are considered as tensors. The polarization is shown lying in the plane of two perpendicular independent vectors...
