1Negative index metamaterials — A negative index metamaterial causes light to refract, or bend, differently than in more common positive refractive index materials. Negative index metamaterials or negative index materials (NIM) are artificial structures where the refractive… …
2Negative refraction — is the name for an electromagnetic phenomenon where light rays are refracted at an interface in the reverse sense to that normally expected. Such an effect can be obtained using a metamaterial which has been designed to achieve a negative value… …
3Optical mapping — Optical mapping[1] is a technique for constructing ordered, genome wide, high resolution restriction maps from single, stained molecules of DNA, called optical maps . By mapping the location of restriction enzyme sites along the unknown DNA of an …
4Optical physics — Optical physics, or optical science, is a subfield of atomic, molecular, and optical physics. It is the study of the generation of electromagnetic radiation, the properties of that radiation, and the interaction of that radiation with matter,… …

6Negative luminescence — is a physical phenomenon by which an electronic device emits less thermal radiation when an electric current is passed through it than it does in thermal equilibrium (current off). When viewed by a thermal camera, an operating negative… …
7Optical relief — (usually noted as simply relief) is a concept in optical mineralogy which refers to the degree in which mineral grains stand out from the mounting medium,[1] usually either oil with a known refractive index or Canada Balsam. Relief is an… …
