Optical Conformal Mapping
TLDR
A general recipe for the design of media that create perfect invisibility within the accuracy of geometrical optics is developed, which can be applied to escape detection by other electromagnetic waves or sound.

Perfect imaging without negative refraction
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 particular, we establish a…

Fiber-Optical Analog of the Event Horizon
TLDR
This work used ultrashort pulses in microstructured optical fibers to demonstrate the formation of an artificial event horizon in optics and observed a classical optical effect: the blue-shifting of light at a white-hole horizon.

Notes on conformal invisibility devices
As a consequence of the wave nature of light, invisibility devices based on isotropic media cannot be perfect. The principal distortions of invisibility are due to reflections and time delays.…

Broadband Invisibility by Non-Euclidean Cloaking
TLDR
Here it is shown that transformation optics of a curved, non-Euclidean space (such as the surface of a virtual sphere) relax these requirements and can lead to invisibility in a broad band of the spectrum.
