1 Erratum to: Appl. Phys. B (2014) 115:155–159 DOI 10.1007/s00340-014-5820-3

In the original publication of the article, signs are incorrect in Eqs. (10), (11) and (15), the symbols \( M^{\prime } \) and \( N^{\prime } \) in Eqs. (12) and (13) should be replaced by \( \varvec{M}^{\prime } \) and \( \varvec{N}^{\prime } \) respectively, the symbols \( \varvec{M}^{\prime } \) and \( \varvec{N}^{\prime } \) in Eqs. (14) and (15) should be replaced by \( M^{\prime } \) and \( N^{\prime } \) respectively, and a phase factor in Eq. (19) is absent.

The correct equations should read:

$$ \tilde{G}_{p, \pm l} = \tilde{G}_{p \pm 1/2, \pm (l - 1)} e^{ \pm i\varphi } = \tilde{G}_{p \pm 1, \pm (l - 2)} e^{ \pm 2i\varphi } , $$
(10)
$$ \tilde{G}_{p, \pm l} = \tilde{G}_{p \mp 1/2, \pm (l + 1)} e^{ \mp i\varphi } = \tilde{G}_{p \mp 1, \pm (l + 2)} e^{ \mp 2i\varphi } , $$
(11)
$$ \varvec{E}^{\prime } = \varvec{E}^{\prime (tm)} + \varvec{E}^{\prime (te)} = \nabla \times \nabla \times \varvec{M}^{\prime } - \partial_{\tau } \nabla \times \varvec{N}^{\prime } , $$
(12)
$$ \varvec{H}^{\prime } = \varvec{H}^{\prime (te)} + \varvec{H}^{\prime (tm)} = \nabla \times \nabla \times \varvec{N}^{\prime } + \partial_{\tau } \nabla \times \varvec{M}^{\prime } , $$
(13)
$$ \varvec{E}^{\prime (tm)} = {- 2\hat{\varvec{e}}_{z} \partial_{{\varsigma_{ + } }} \partial_{{\varsigma_{ - } }} M^{\prime }} + \left( {w_{w} /z_{D} } \right){\kern 1pt} \left( {\hat{\varvec{e}}_{R} \partial_{{\varsigma_{ + } }} + \hat{\varvec{e}}_{L} \partial_{{\varsigma_{ - } }} } \right)\partial_{z} M^{\prime } , $$
(14)
$$ \varvec{E}^{\prime (te)} = - i\left( {w_{w} /z_{D} } \right)\left( {\hat{\varvec{e}}_{R} \partial_{{\varsigma_{ + } }} - \hat{\varvec{e}}_{L} \partial_{{\varsigma_{ - } }} } \right)\partial_{\tau } N^{\prime } , $$
(15)
$$ \varvec{E}_{p, \pm l}^{(te)} = i\hat{\varvec{e}}_{\phi } \left( {f^{ - 1} Q_{p,l + 1} - f^{ + 1} {\kern 1pt} Q_{p + 1,l + 1} } \right){\kern 1pt} e^{ \pm il\varphi } . $$
(19)

Above corrections do not affect other equations.
