Refer to Chap. 9 in p.353 - p.368.
typedis means the type of dispersive model.
N means the number of poles in this material.
εr,∞ is the relative permittivity at infinite frequency,
μr is relative permeability,
σE is electric conductivity,
and σH is equivalent magnetic loss, respectively.

\varepsilon(\omega) = \varepsilon_\infty + \sum_{p=1}^P \chi_p(\omega)

Debye model: \chi_p(\omega) = \frac{\Delta\varepsilon_{p}}{1+j\omega\tau_p}

Lorentz model: \chi_p(\omega) = \frac{\Delta\varepsilon_{p} \omega_p^2}{\omega_p^2+2j\omega\delta_p-\omega^2}

Drude model: \chi_p(\omega) = -\frac{\omega_p^2}{\omega^2-j\omega\gamma_p}
