Abstract

This erratum corrects minor errors in the paper.

This letter [Optical Engineering, 59(7), 070503 (2020) DOI: 10.1117/1.OE.59.7.070503] was originally published on 24 July 2020 with an error in Eq. (4).

The incorrect equation appeared as:

Eq. (4)

{\underline{\underline{ε}}}_{g} (x, z) = {\begin{cases} ε_{d} \underline{\underline{I}} - (ε_{d} \underline{\underline{I}} - {\underline{\underline{ε}}}_{CTF}) U [L_{g} - z - g (x)], & x \in [0, L_{1}], \\ {\underline{\underline{ε}}}_{CTF}, & x \in [L_{1}, L], \end{cases}, z \in (L_{c}, L_{c} + L_{g}),

The corrected equation appears as:

Eq. (4)

{\underline{\underline{ε}}}_{g} (x, z) = {\begin{cases} ε_{d} \underline{\underline{I}} - (ε_{d} \underline{\underline{I}} - {\underline{\underline{ε}}}_{CTF}) U [L_{g} + L_{c} - z - g (x)], & x \in [0, L_{1}], \\ {\underline{\underline{ε}}}_{CTF}, & x \in [L_{1}, L], \end{cases}, z \in (L_{c}, L_{c} + L_{g}) .

Also, in the first paragraph in Sec. 3.1, the conditions on imaginary part of $α$ were incorrectly stated. The correct conditions are $Im (α) < 0$ in the CTF and $Im (α) > 0$ in the isotropic dielectric material.

These errors were not present in the computations and all results in the letter remain correct.

The paper was corrected on 24 June 2021.
