Definition: the limit of the natural logarithm of the ratio of values at a given frequency of a specified component of an electromagnetic field at two points aligned in the direction of propagation of a guided or plane wave or of a wave practically plane in a limited space domain divided by the distance between the two points when this distance tends to zero

NOTE – The propagation coefficient is a complex quantity usually a function of frequency and has the dimension of reciprocal length.
