Refer to Chap. 9 at 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.

non-dispersive 0 0 0 0 0
Debye 1 εs,p ε∞,p τp 0
Lorentz 2 εs,p ε∞,p ωp δp
Drude 3 ωi γp 0 0

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

Debye model: \chi_p(\omega) = \frac{(\varepsilon_{s,p}-\varepsilon_{\infty,p})}{1+j\omega\tau_p}

Lorentz model: \chi_p(\omega) = \frac{(\varepsilon_{s,p}-\varepsilon_{\infty,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}
