In our previously published paper , we derive an analytical expression of the field-overlap of a Gaussian beam with a simplified surface plasmon field in Appendix A. Equations (A7), (A9), and (A16) have minor errors of factors of 2. Equation (A7) should read
The main result of the field-overlap derivation, given by Eq. (A18), is expressed correctly in the original paper . The analysis and conclusions which use the derivation are thus unaffected by the corrections.
