Simulation1DLayered.compute_complex_sigma(frequencies)

Computes the complex conductivity matrix using Pelton’s Cole-Cole model:

\[\sigma (\omega ) = \sigma \Bigg [ 1 - \eta \Bigg ( \frac{1}{1 + (1-\eta ) (1 + i\omega \tau)^c} \Bigg ) \Bigg ]\]

Parameters:

frequencies (numpy.array) – np.array(N,) containing frequencies

Return type:

numpy.ndarray: np.array(n_layer, n_frequency)

Returns:

complex conductivity matrix
