Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive … Ver mais A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. Uniaxial materials The simplest type of … Ver mais While the best known source of birefringence is the entrance of light into an anisotropic crystal, it can result in otherwise optically isotropic materials in a few ways: • Stress birefringence results when a normally isotropic … Ver mais Birefringence and other polarization-based optical effects (such as optical rotation and linear or circular dichroism) can be observed by measuring any change in the polarization of light … Ver mais In an isotropic medium (including free space) the so-called electric displacement (D) is just proportional to the electric field (E) according to D = ɛE where the material's permittivity ε is just a scalar (and equal to n ε0 where n is the index of refraction). … Ver mais Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some … Ver mais The best characterized birefringent materials are crystals. Due to their specific crystal structures their refractive indices are well defined.
