k⋅D=0{\displaystyle \mathbf {k} \cdot \mathbf {D} =0} (4b) Eq. 4bindicates that Dis orthogonal to the direction of the wavevector k, even though that is no longer generally true for Eas would be the case in an isotropic medium. Eq. 4bwill not be needed for the further steps in the following derivation. Visa mer 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 … Visa mer Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some terminology in use. Isotropic materials have symmetry in all directions and the refractive index is the same for any … Visa mer The best characterized birefringent materials are crystals. Due to their specific crystal structures their refractive indices are well defined. Depending on the symmetry of a … Visa mer Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to become lighter or darker through rotation of the polarization (circular birefringence) of linearly polarized light as viewed … Visa mer 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 birefringence is described as … Visa mer 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 … Visa mer 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 passing through the material. These measurements are known as Visa mer WebbAbstract. When bone is exposed to the burial environment it may experience structural changes induced by multiple agents.
