W. Harshawardhan et al., Numerical solution of the time-dependent Maxwell's equations for random dielectric media, PHYS REV E, 62(6), 2000, pp. 8705-8712
We discuss how a spectral-domain method in combination with a split-operato
r technique can be used to calculate exact solutions of the time-dependent
Maxwell's equations. We apply this technique to study the tunneling signal
of an evanescent wave occurring due to frustrated total internal reflection
and the propagation of a light pulse through an inhomogeneous medium consi
sting of multiple random scatterers.
