Notes

The propagation coefficient is given by:

γ = α + i β

where $α$ denotes attenuation (attenuation) and $β$ the phase coefficient (phase coefficient) of a plane wave.

L'exposant linéique de propagation est donné par:

γ = α + i β

où $α$ désigne l'affaiblissement linéique (attenuation) et $β$ le déphasage linéique (phase coefficient) d'une onde plane.
