propagation constant meaning

• [Electronics]
  For waves transmitted along a line, a number showing the effect the line has on the wave. This is a complex figure [i.e., one containing a real-number component (the attenuation constant) and an imaginary-number component (the phase constant)].
  

• As a result, it represents the propagation constant in the periodic medium.
• Waveguide dispersion is dependent on the propagation constant.
• The propagation constant \ gamma of the guided wave is complex, in general.
• The propagation constant of the polaritons can be modified by varying the dielectric material.
• We can call this K ( w ) a propagation constant in line with Futterman.
• The propagation constant is a useful concept in filter design which invariably uses a cascaded section topology.
• Below a certain frequency ( the cut-off frequency ) the propagation constant becomes an imaginary number.
• The following result can be applied at any point along the transmission line, where gamma is defined as the propagation constant.
• The term " propagation constant " is somewhat of a misnomer as it usually varies strongly with " � ".
• One such example, dual polarisation interferometry uses a buried waveguide as a reference against which the change in propagation constant is measured.

• "propagation constant" meaning in Chinese: 传播常量
• "propagation constant" meaning in Japanese: propagation constant 伝搬定数[基礎]; 伝搬定数[電情]; 伝搬定数[機械]
• "propagation constant" meaning in Russian: радио постоянная передачи, постоянная распространения
