Ulf Leonhardt, Thomas Philbin
is scheduled for NJP, August 2007 edition

but you can read it at
http://www.arxiv.org/abs/quant-ph/0608115

they also published
http://www.arxiv.org/abs/0707.3686  and
http://www.iop.org/EJ/abstract/1367-2630/8/10/247

(no idea about these invisibility devices,
optical Aharonov-Bohm effects, negative
refraction space-time transformations, etc.)
