 1. (general) The real part of the propagation constant ; unit Neper per unit length. 2. (fiber optic) For a particular mode, the real part of the axial propagation constant. the attenuation coefficient for the mode power is twice the attenuation constant. IEEE std100 812-1984
 3. (waveguide) The rate of decrease in  amplitude of a field component of a traveling wave in a uniform transmission line at a given frequency in the direction of propagation as a function distance ; the real part of the propagation constant. IEEE (MTT) 146-1980w
