Static dielectric constant and High Frequency dielectric constant

[Inaoton]

Hello,
             An anisotropic material has three components of real and imaginary parts(x.y.z) of the dielectric tensor in Optical spectrum .
            1.  How can i measure the static dielectric constant of the anisotopric material?
            2. Similarly how can i measure the high frequency dielectric constant?

Do you mean how these can be experimentally measured? If so, you may google this kind of information, e.g., see https://www.google.dk/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=measure+dielectric+constant&*.

or use OpticalSpectrum analysis in ATK to calculate it: http://docs.quantumwise.com/manuals/Types/OpticalSpectrum/OpticalSpectrum.html

Good Morning,

more in general, how to calcualte with QW the dielectric constant vs. frequency, from microwave to optics, of a material ?
For example, how to re-obtain the Kubo-Drude formula for monolayer graphene ?
