I don't know what units you're using, but 35 sounds like the relative dielectric constant. If you want the actual dielectric constant multiply by 8.85E-14 F/cm

the best way is to make measurements directly. Another way is to make a calculation.
So you must measure the conductivity loss and impedance over the frequency. Then you can use a description of Z is dependence of eps, mue and kappa. If you like to have the permeability you can calculate.
If you mean by the permittivity material the absolute permittivity then the unit si F/m and the dielectric constant or relative permittivity (without unit) is obtained by:
