Hi there!
I have a question about the classical interaction of light with matter according the Drude-Lorentz model. Let's suppose that the light in matter has a wave-number k which in general is complex. Then the real part of k accounts for the propagation of light, while the imaginary part of k is a dumping factor. Can I figure out the behavior of light? I mean, e.g. if [tex]Re(k)=0[/tex] and [tex]Im(k)\neq0[/tex] then I have an evanescent wave: does this mean that light is absorbed or reflected?
Thank you
