From the dielectric constant vs wavelength curve can we get idea, atleast qualitatively, about the conducting (or inslating) nature of the material?

We have calculated the dielectric constant of TiO2 film from the value of n anbd k using the optical reflectance data. We did not carry out any electrical measurement. From the dielectric values...
