Talk:Dispersive Material Property

I found that in some physics textbooks the Drude function is: $$\epsilon = 1 - \frac{\omega_p^2}{\omega^2 + i \gamma \omega}$$, and the wikipedia page of permittivity says that researchers in physics use $$e^{-i\omega t}$$ for time-denpendence, but in engineering $$e^{i\omega t}$$ is used. Maybe it should be point out.

You are right, maybe you want to add this to section 4?

Please keep in mind, that most of the dispersive materials will be supported only in the next release version. You can download a dev-snapshot here: or
