Propagation — can refer to:*Reproduction, and other forms of multiplication or increase **Plant propagation, the production of more plants by seeds, cuttings, grafting or other methods **Propagation of schema, in artificial reproduction *Wave propagation, the… … Wikipedia
Propagation constant — The propagation constant of an electromagnetic wave is a measure of the change undergone by the amplitude of the wave as it propagates in a given direction. The quantity being measured can be the voltage or current in a circuit or a field vector… … Wikipedia
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
Radio propagation — is a term used to explain how radio waves behave when they are transmitted, or are propagated from one point on the Earth to another. [ H. P. Westman et al, (ed), Reference Data for Radio Engineers, Fifth Edition , 1968, Howard W. Sams and Co.,… … Wikipedia
Lamb waves — propagate in solid plates. They are elastic waves whose particle motion lies in the plane defined by the plate normal and the direction of wave propagation. In 1917, the English mathematician Horace Lamb published his classic analysis and… … Wikipedia
Dispersion (water waves) — This article is about dispersion of waves on a water surface. For other forms of dispersion, see Dispersion (disambiguation). In fluid dynamics, dispersion of water waves generally refers to frequency dispersion, which means that waves of… … Wikipedia
Boussinesq approximation (water waves) — In fluid dynamics, the Boussinesq approximation for water waves is an approximation valid for weakly non linear and fairly long waves. The approximation is named after Joseph Boussinesq, who first derived them in response to the observation by… … Wikipedia
Radio waves — are electromagnetic waves occurring on the radio frequency portion of the electromagnetic spectrum. A common use is to transport information through the atmosphere or outer space without wires. Radio waves are distinguished from other kinds of… … Wikipedia
Wave propagation — is any of the ways in which waves travel through a waveguide.With respect to the direction of the oscillation relative to the propagation direction, we can distinguish between longitudinal wave and transverse waves.For electromagnetic waves,… … Wikipedia
Line-of-sight propagation — refers to electro magnetic radiation including light emissions traveling in a straight line. The rays or waves are diffracted, refracted, reflected, or absorbed by atmosphere and obstructions with material and generally cannot travel over the… … Wikipedia
