Dear all,

Does anyone know where I can obtain the far-infrared(THz) optical
constant(complex index of refraction,n-ik)of metals? I also try to
calculate the real and imaginary part of the complex index of refraction of
some metals as a function of wavelength (from 30 to 300 um)by using Drude
model, but this requires me to know some parameters for different metals:
such as the relaxation time, effective mass of electron,or electrical
conductivity. I also have difficulty in finding these data. Could you
please give me a hand?? Many thanks.
