Wilson's model
for a $\exp(-j\omega t)$ convention :| $ \widetilde{\rho}(\omega) = \rho_{\infty} \displaystyle{\frac{(1-j\omega\tau_{\textrm{vor}})^{1/2}} {(1-j\omega\tau_{\textrm{vor}})^{1/2}-1}} $ | (1) |
2 parameters.
| $ \widetilde{K}(\omega) = K_{\infty} \displaystyle{\frac{(1-j\omega\tau_{\textrm{ent}})^{1/2}} {(1-j\omega\tau_{\textrm{ent}})^{1/2}+\gamma-1}} $ | (2) |
2 parameters.
