Since the publication of the original article [1], one of the authors noticed a typographical error to equations (11a) and (11b) in their published article [1]. The correct versions of (11a) and (11b) are included in this Correction article.
$$\begin{aligned} &C_{m}\omega_{m}= \frac{1}{\sqrt{Z_{0} R_{c}}} \sqrt{1 - \frac{Z_{0}}{R_{c}}} , \\ &L_{m}\omega_{m}= \sqrt{Z_{0} R_{c}} \sqrt{1 - \frac{Z_{0}}{R_{c}}}, \end{aligned}$$
