Abstract :
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.
