the nonlinear-FDTD codes reported is almost in form of
d(D)/dt=****
and then set electric field E=D/epsilon0/epsilonR, D:electric displacement
where epsilonR is related to Kerr effect or Raman effect
however for lossy material, d(D)/dt-sigmaE*E=***, sigmaE is the conductivity of material.
and sigma is related to electric field? in this case how to handle sigmaE*E in form of D?
is it possible to set sigmaE*E in form of sigmaD*D? but how to get the value of sigmaD?
do I make myself clear?[/code]
