Path loss — (or path attenuation) is the reduction in power density (attenuation) of an electromagnetic wave as it propagates through space. Path loss is a major component in the analysis and design of the link budget of a telecommunication system.This term… … Wikipedia
Refraction — For the property of metals, see refraction (metallurgy). For the magic effect, see David Penn (magician). For the refraction in atmosphere, see Atmospheric refraction. Light on air–plexi surface in this experiment mainly undergoes refraction… … Wikipedia
Refraction — In ophthalmology, the bending of light that takes place within the human eye. Refractive errors include nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. Lenses can be used to control the amount of refraction, correcting… … Medical dictionary
refraction — noun Date: 1603 1. deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (as air) into another (as glass) in which its velocity is different 2. the change in the apparent position of a… … New Collegiate Dictionary

Optical path length — In optics, optical path length (OPL) or optical distance is the product of the geometric length of the path light follows through the system, and the index of refraction of the medium through which it propagates. A difference in optical path… … Wikipedia
Optical path — The path that light takes in traversing an optical system is often called the optical path. The physical length of an optical device can be reduced to less than the length of the optical path by using folded optics. The optical path length as… … Wikipedia
optical path — the path of light through a medium, having a magnitude equal to the geometric distance through the system times the index of refraction of the medium. [1890 95] * * * … Universalium
Non-line-of-sight propagation — Non line of sight (NLOS) or near line of sight is a term used to describe radio transmission across a path that is partially obstructed, usually by a physical object in the innermost Fresnel zone. Many types of radio transmissions depend, to… … Wikipedia
