These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between … Zobacz więcej 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 … Zobacz więcej 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: Zobacz więcej 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 Zobacz więcej 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 Zobacz więcej Much of the work involving polarization preceded the understanding of light as a transverse electromagnetic wave, and this has affected … Zobacz więcej The best characterized birefringent materials are crystals. Due to their specific crystal structures their refractive indices are well … Zobacz więcej Birefringence is used in many optical devices.

So far, we have assumed that refraction is given by linear equations involving a spatially constant, scalar refractive index. These assumptions can break down in different ways, to be described in the following subsections. In some materials, the refractive index depends on the polarization and propagation direction of the light. This is called birefringence or optical anisotropy. WitrynaDescription. ridx = refractiveidx (h) calculates the refractive index ridx at height h above mean sea level (MSL) using the International Telecommunication Union (ITU) standard atmospheric model. ridx = refractiveidx ( ___,Name,Value) calculates the refractive index with additional options specified by one or more name-value pairs.
