Dielectric measurements

Is there a clear and definite way to get complex dielectric permittivity measurements from TDR?

Is there a method for using the TDR waveform to extract the frequency-dependence of the dielectric constant?

These two references address the question:
"Is there a method for using the TDR waveform to extract the frequency-dependence of the dielectric constant?"
