Perfect imaging without negative refraction
Ulf Leonhardt
Perfect imaging has been believed to rely on negative refraction, but here we show that an ordinary positively-refracting optical medium may form perfect images as well. In particu…

An omnidirectional retroreflector based on the transmutation of dielectric singularities
Yun Gui Ma, C. K. Ong, Tomas Tyc +1
In the field of transformation optics, metamaterials mimic the effect of coordinate transformations on electromagnetic waves, creating the illusion that the waves are propagating t…

Casimir-Lifshitz force between moving plates at different temperatures
T. G. Philbin, U. Leonhardt
The zero-temperature Casimir-Lifshitz force between two plates moving parallel to each other at arbitrary constant speed was found in [New J. Phys. 11, 033035 (2009)]. The solution…
