Home > Propagation

• Multiplication or increase, as by natural reproduction.
• In genetics, propagation is another term for the elongation part of transcription.
• In agriculture and horticulture, propagation is the production of increased numbers of plants, by seeds, cuttings, grafting or other methods.
• In religion, propagation is a term often used for winning new converts to the particular religion.
• In physics, propagation is the motion of waves through or along a medium.

Note: For electromagnetic waves, propagation may occur in a vacuum as well as in material media.

Propagation constantFor an electromagnetic field mode varying sinusoidally with time at a given frequency, the propagation constant is the logarithmic rate of change, with respect to distance in a given direction, of the complex amplitude of any field component. Note: The pr Propagation path obstructionIn telecommunication, a propagation path obstruction is a man-made or natural physical feature that lies near enough to a radio path to cause a measurable effect on path loss, exclusive of reflection effects. Note: An obstruction may lie to the side, abov PropagationThe word propagation can mean: Multiplication or increase, as by natural reproduction. In genetics, propagation is another term for the elongation part of transcription. In agriculture and horticulture, propagation is the production of increased numbers o Propagation modeA propagation mode is a way in which a radio signal is propagated from the transmitter to the receiver. Some examples are tropospheric ducting and sporadic E-skip, which bring in stations from long distances. Radio frequency propagation. Propagation of errors resulting from algebraic manipulationsIn statistics propagation of errors means to calculate the error on a quantity f from (usually measured) other quantities x and the knowledge of how to compute f from the x''. General formula Given a function f ''x ''x . which depends on N uncorrelated va
