In the Letter in question [1], numerical errors have occurred in the computations of the theoretical magnitude cross-sectional profiles for the electric and magnetic field components of a high-order Bessel vortex beam of fractional type $\alpha$, displayed in Figs. 1 and 2. The corrected computational plots that should replace Figs. 1 and 2 in [1] are presented herein. The other published plots in Fig. 3 of [1] are correct and do not require any adjustment.

 

Fig. 1. Theoretical magnitude cross-sectional profiles for the electric (a) and magnetic (b) field components along the axes $x$, $y$, $z$ (represented along each column) of an EM HOBVB-F$\alpha$ for $\alpha =5$ and $k/k_r=2.3662$. When $\alpha$ becomes fractional ($=5.5$), the electric (c) and magnetic (d) field components exhibit specific patterns in which the symmetry is broken.

Fig. 2. Same as in Fig. 1; however, $k/k_r=1.1547$.

The new corrected plots do not alter the discussions and conclusions presented in [1].
