PET, Polyethylene terephthalate, I want to know how to obtain the parameters of the lorentz oscillator, for this material, PET, a material that requires an extra complexity not to be pure, like gold or aluminum Sorry for bad English.

Basically, my study is to draw a permissivity curve by frequency, using the Lorentz oscillator, I need some parameters, such as plasma frequency and resonance frequency of the material, I can not find in the literature the frequency of resonance of the PET material

Telecommunications engineering student at UFSJ, Brazil, research area: metamaterials, applied electromagnetism

The frequency of plasma already achieved ... in a study, is presented the resonance frequency in eV, how to obtain in Hz? Wo = 7eV
