Abstract

In a previous paper [Opt. Lett. 37, 2787–2789 (2012)], several typos have been found. Results of the paper remain unchanged.

The following typos have been found in [1].

* The correct form of Eqs. (5) and (6) is $E_{1} = (e^{i k x} - e^{- i k x}) \frac{1}{\sqrt{2}} (0, 1, i),$ $E_{2} = (e^{i k y} - e^{- i k y}) \frac{1}{\sqrt{2}} (1, 0, i) e^{i ϕ} .$
* The correct form of Eqs. (11) and (12) is $〈 F_{x} 〉 = - α^{''} k ϵ_{0} [\cos (k x) \sin (k y)],$ $〈 F_{y} 〉 = α^{''} k ϵ_{0} [\cos (k y) \sin (k x)] .$
* Points with zero scattering force are also given by Eq. (14), $m_{1}$ and $m_{2}$ being semi-integer numbers.
