Transmission coefficient — right|frame|An electromagnetic (or any other) wave experiences partial transmittance and partial reflectance when the medium through which it travels suddenly changes.The transmission coefficient is used in physics and electrical engineering when … Wikipedia
Transmission — is the act of passing something on.Specifically, it may refer to:*Transmission (mechanics), a gear system transmitting mechanical power, as in a car *Transmission (telecommunications), the act of transmitting messages over distances *Transmission … Wikipedia
Coefficient — For other uses of this word, see coefficient (disambiguation). In mathematics, a coefficient is a multiplicative factor in some term of an expression (or of a series); it is usually a number, but in any case does not involve any variables of the… … Wikipedia
Transmission electron microscopy — A TEM image of the polio virus. The polio virus is 30 nm in size.[1] Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it… … Wikipedia
Reflection coefficient — The reflection coefficient is used in physics and electrical engineering when wave propagation in a medium containing discontinuities is considered. A reflection coefficient describes either the amplitude or the intensity of a reflected wave… … Wikipedia
Physical coefficient — A physical coefficient is an important number that characterizes some physical property of a technical or scientific object. A coefficient also has a scientific reference which is the reliance on force. To find the coefficient of a chemical… … Wikipedia
Standing wave ratio — In telecommunications, standing wave ratio (SWR) is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR is usually defined as a … Wikipedia
High-resolution transmission electron microscopy — (HRTEM) is an imaging mode of the transmission electron microscope (TEM) that allows the imaging of the crystallographic structure of a sample at an atomic scale. [cite book |title=Experimental high resolution electron microscopy |last=Spence… … Wikipedia
LIGNES DE TRANSMISSION — On appelle ligne de transmission un ensemble de conducteurs cylindriques à génératrices parallèles qui assure le transport de l’énergie électrique entre deux points donnés. Les lignes de transmission présentent une diversité très grande selon les … Encyclopédie Universelle
Metal-mesh optical filters — are optical filters made from stacks of metal meshes and dielectric. They are used as part of an optical path to filter the incoming light to allow frequencies of interest to pass while reflecting other frequencies of light. Metal mesh filters… … 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
