PT-symmetric metamaterial systems for aberration-free imaging and wave manipulation

We show that PT-symmetry concepts, combined with an effective nonlocal response, allow realizing all-angle negative refraction and aberration-free optical imaging. The designed PT-symmetric lens is an example of "absolute optical instrument", with similar imaging properties as DNG lenses,...

Summary:We show that PT-symmetry concepts, combined with an effective nonlocal response, allow realizing all-angle negative refraction and aberration-free optical imaging. The designed PT-symmetric lens is an example of "absolute optical instrument", with similar imaging properties as DNG lenses, but without some of their drawbacks.
