Short summary
A relatively simple numerical method is introduced to separate the electric conductivity from the effective (complex) permittivity. The latter is often the outcome of measurements of the electric properties of a material. The method includes a numerical evaluation of the Kramers-Kronig transform integrals also known as Hilbert transform. Exemplarily it is applied to extract the conductivity from measured data found in the literature describing the effective permittivity of composite material.
