Slow Time-Scale Source-Free Maxwell Equations for a Nonstationary, Inhomogeneous Medium.

Abstract

Source-free Maxwell equations are derived for n electromagnetic (carrier) wave in an inhomogeneous medium exhibiting nonstationary linear response. The non-stationarity is assumed to be slow in comparison with the carrier oscillation, and the equations that result assume that time-derivatives of all slowly varying quantities higher than the first order can be neglected. The equations form the theoretical basis of analysis of the nonlinear dynamics of the coupling of laser energy into a fluid, for the case of the laser intensity below threshold for air (plasma) breakdown.
