propagation Telecom Definition

The movement of waves, such as electromagnetic waves, through a medium or through free space.

propagation Usage Examples

Preposition: of

  • wave: Zero mass density is the condition for the propagation of waves at infinite speed.
  • pulse: In addition, the propagation of intense laser pulses through capillary tubes was undertaken.
  • crack: Propagation of these cracks is dependent on an energy balance, which leads to a critical crack length.

Converse of object

simulate: The project will combine analytical studies and numerical modeling tools for simulating wave propagation in fractured porous rock.

Adjective modifier

  • vegetative: Has there been subsequent vegetative propagation of material derived from seed?
  • clonal: Clonal propagation -- asexual reproduction, including vegetative spread, producing a clone of the parent plant.
  • anomalous: Weather section states no anomalous propagation or northern light.
  • ultrasonic: Of particular interest is the modeling of ultrasonic wave propagation through heterogeneous media.
  • electromagnetic: In 1899, Fitzgerald asked him about electromagnetic wave propagation around a sphere, which Marconi's experiments showed to occur.
  • transient: Swaffield J.A. , and Campbell D.P. ` The simulation of air pressure transient propagation in building drainage and vent systems ' .

Modifies a noun

  • velocity: Signal propagation velocity In drift chambers it takes time for the charge to propagate along the sense wires.
  • delay: The huge distances covered by the signal result in propagation delays of up to 5 seconds.
  • prediction: Guided waves, ground waves, sky waves and space waves are covered, and propagation prediction techniques described.
  • algorithm: Some of the cases are reserved, and not actually used for training in the back propagation algorithm.

Noun used with modifier

  • ionospheric: Real-time dynamic system for monitoring ionospheric propagation conditions over europe.
  • radiowave: The topics covered range from antennas, through radiowave propagation, optics and radar, to communications signal processing and networks.
  • crack: There is very little crack propagation with such slow cycles.
  • wave: Both use an ultrasonic wave propagation sensor mounted in the liquid medium.
  • pulse: We are applying these methods to study ultrashort pulse propagation within the cavity of semiconductor lasers.
  • flame: Flame propagation was over 20 times faster at 60° , than horizontal.
