Conventional transformation optics is based on real-valued spatial coordinate transformations which cannot naturally handle nonlocal (spatial dispersion) and gain/loss effects. Here, we review some recent attempts to extend the approach to engineer nonlocal and non-Hermitian effects in metamaterials.

Abstract
Conventional transformation optics is based on real-valued spatial coordinate transformations which cannot naturally handle nonlocal (spatial dispersion) and gain/loss effects. Here, we review some recent attempts to extend the approach to engineer nonlocal and non-Hermitian effects in metamaterials.File in questo prodotto:
