LorentzPole¶

Type:	section
Appearance:	multiple

LorentzPole model of the permittivity:

$\begin{eqnarray*} \TField{\varepsilon}^{(\mathrm{rel})} & = & \Delta_{\varepsilon}\frac{\omega_{p}^2}{\omega_{p}^2-2i\omega\gamma-\omega^2} \end{eqnarray*}$

A LorentzPole permittivity is parameterized by the following parameters

the Damping $\gamma$ in $[rad/s]$ ,
the ResonanceFrequency $\omega_p$ in $[rad/s]$ ,
the scalar Shift $\Delta_{\varepsilon}$ .

An example of a permittivity described by multiple oscillators is the following section:

RelPermittivity {
  LorentzPole {
    Damping = 0
    ResonanceFrequency = 1.07e+16
    Shift = 0.3306
  }
  LorentzPole {
    Damping = 0
    ResonanceFrequency = 1.77e+16
    Shift = 4.3356
  }
  Constant = 1
}

Note

Please note units and parameterisation of the permittivity model.
