Simulation1DLayered.compute_complex_sigma(frequencies)[source]#

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

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

Parameters:

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

Return type:

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

Returns:

complex conductivity matrix
