Transformation devices with optical nihility media and reduced realizations
Lin Xu, Qiannan Wu, Yangyang Zhou +1
Starting from optical nihility media (ONM), we design several intriguing devices with transformation optics method in two dimensions, such as a wave splitter, a concave lens, a fie…

Revisit the carpet cloak from optical conformal mapping
Hui Li, Yadong Xu, Qiannan Wu +1
The original carpet cloak [Phys. Rev. Lett. 101, 203901 (2008)] was designed by a numerical method, the quasi-conformal mapping. Therefore its refractive index profile was obtained…

Cloaking and imaging at the same time
Qiannan Wu, Yadong Xu, Huanyang Chen
In this letter, we propose a conceptual device to perform subwavelength imaging with positive refraction. The key to this proposal is that a drain is no longer a must for some case…
