Critique of optical negative refraction superlensing [PDF]

, 2011
Has the ten-year old quest for the optical superlens, based on Veselago’s hypothesis of negative refraction, been a chimera? We argue that Pendry’s alternative prescription of the silver superlens is nothing more than an application of the natural ...

Ray-optical refraction with confocal lenslet arrays [PDF]

, 2008
Two parallel lenslet arrays with focal lengths f1 and f2 that share a common focal plane (that is, which are separated by a distance f1+f2) can refract transmitted light rays according to Snell's law, but with the 'sin's replaced with 'tan's. This is the
