Wave Propagation Parameters

Can also be called "Propagation constant". Somewhat misleading, as the propagation usually varies strongly.

Alternative names:

  • Transmission parameters
  • Propagation parameters
  • Propagation coefficients
  • Transmission constants
  • Secondary coefficients

Propagation constant, symbol γ, is defined by the ratio between the amplitude at the source, and the amplitude at some distance x. Is a complex quantity, so we use α (attenuation constant) and β (phase constant) to define it. Attenuation constant, is the loss of signal, or attenuation of an electromagnetic wave travelling through a medium. Phase constant is the change in phase per meter, along the path travelled.
