Radiative transfer equations in broad-band, time-varying fields
Abstract
A derivation of the equation of transfer is obtained by starting with Maxwell's equations in the "slowly varying envelope" form. Particular attention is paid to characterizing the intensity that is "seen" by the atom (which is found to be related to a Wigner distribution of the electric field). The equation of transfer is found to be valid for "broad-band" slowly varying radiation fields.
