Vector photochromism in polarization-sensitive materials

Optics Letters, 2014
The phenomenon of vector photochromism was observed in some high-efficient polarization-sensitive materials depending on the radiant exposure of the inducing linearly polarized actinic light. The phenomenon has the purely vector nature because the absorption of the irradiated and unirradiated areas of the material is practically identical when we use ...

Reflection and Polarization Properties of Powder Materials

Applied Optics, 1967
Directional radiance factors and polarization are presented for pure silicon carbide powder with an average albedo of 0.15 over a size range from 8 micro to 86 micro, pure aluminum oxide powder with average albedo about 0.85 over a size range from 0.1 micro to 86 micro, and for a mixture of one part silicon carbide to six parts aluminum oxide with ...

The peculiarities of polarization bistability, realized in polarization-sensitive materials

SPIE Proceedings, 2011
The paper proposes for consideration an alternative method of creating systems for processing and preserving information on the basis of molecular crystals using the phenomenon of optical bistability. Polarization-dependent nonlinear absorption of the benzene type molecular crystals is responsible for the complex dynamics of exciton processes in the

Multi-functional Materials with Polarization

2007 Sixteenth IEEE International Symposium on the Applications of Ferroelectrics, 2007
Multifunctional materials can respond to more than one external stimulus. One important family of such materials would be those with magnetization-polarization interactions: however, prior searches for such systems with strong exchange have proven elusive.

Polarization of Light by Circumstellar Material

Publications of the Astronomical Society of the Pacific, 1972
The same circumstellar material that produces infrared excesses in stars will, in the case of favorable geometry and optical depth, give rise to linear polarization at optical wavelengths by scattering of the stellar radiation. Such intrinsic stellar polarizations may be distinguished from the interstellar component by time variability, by a wavelength

Material Polarization and Dispersion

1992
The present chapter is designed to serve as a bridge between the polarization discussion of Chapter 2 and the anisotropie propagation theme of Chapter 4, as well as to stand on its own as adescription of the relationship between the microscopic and the macroscopic pictures of the interaction of light and matter.

Polarization Switching for Ferroelectric Materials

Aerospace, 1996
Abstract In this paper we present the results of an experimental study focused on understanding the strain concentrations arising due to nonlinear phenomena associated with polarization switching. A Moire interferometry technique is used to measure the normal and shear strains of a PZT-5H piezoceramics undergoing 180° and 90° switching ...

YPHON: A package for calculating phonons of polar materials

Computer Physics Communications, 2014
Abstract In our recent works, we have developed a mixed-space approach within the framework of direct method for the first-principle calculation of phonon properties. It makes full use of the accuracy of the force constants calculated in the real space and the dipole–dipole interactions in the reciprocal space, making the accurate phonon calculation ...

Magnetic polarization of material

2001
Abstract In the same manner that electrically polarizable material complicated the application of Gauss’s law in electrostatics, the presence of magnetically polarizable material complicates the application of Ampe’re’s law in magnetostatics.
