Abstract

An erratum is presented to correct equations (10a), (11a) and (11b) in [Opt. Express 17, 1308–1320 (2009)].

© 2009 Optical Society of America

The corrections of typographical errors of equations (10a), (11a) and (11b) in Ref. [1] should be like the following forms:

λr=drdr=(ba)r2ab2,
εr=μr=λrλθλϕ=b2(ra)2ar2(ba),
εθ=μθ=εϕ=μϕ=λθλϕλr=ab2(ba)r2

The authors regret this mistake, which does not affect any numerical result presented or conclusions reached in Ref. [1].
