According to the procedure outlined above this value has been introduced into Eq.
WebThe refractive index of extraordinary rays varies since it is composed of epsilon_11 and epsilon_33 which are not equal, and their combination depends on the angle of polarization and propagation. By adjusting the angle of incidence, the effective refractive index of the extraordinary ray can be tuned in order to achieve phase matching, which is required for the efficient operation of these devices. Medicine. Birefringence is utilized in medical diagnostics. See more 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 … See more Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected some … See more 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 … See more 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 … See more A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the … See more While the best known source of birefringence is the entrance of light into an anisotropic crystal, it can result in otherwise See more 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 … See more
