All-angle negative refraction without negative effective index

Chiyan Luo, Steven G. Johnson, J. D. Joannopoulos and J.B. Pendry

Abstract:

We describe an all-angle negative refraction effect that does not employ a negative effective index of refraction and involves photonic crystals. A few simple criteria sufficient to achieve this behavior are presented. To illustrate this phenomenon, a microsuperlens is designed and numerically demonstrated.
