The choice of this convention is dictated by the simplicity of the transformation demonstrated later. -α is equal to β, the phase defined by J. M. Bennett in J. Opt. Soc. Am. 54, 612 (1964).

w0 is a part of the total energy density, the other part corresponds to the potential and kinetic energy of the dipoles.
This definition of w0 and S, as pointed out by many authors, is not unique, but the expressions adopted are the simplest and no disagreement with experiment has ever been found.
