Capacitor Reflectance

For a capacitor of $C$ Farads, the driving-point impedance is (see §7.1.3)

$$R_C(s)=\frac{1}{Cs}$$

(or $k/s$ for a spring with constant $k$ ). Substituting into Eq.(F.1) gives the reflectance

$$\hat{\rho}_C(s) = \frac{R_C(s)-R_0}{R_C(s)+R_0} = \frac{1 - R_0 C s}{1 + R_0 C s} \protect$$ (F.2)
