We introduce a complex-coordinate extension of the transformation-optics approach which enables for the generation and modeling of a general class of metamaterials with balanced loss and gain characterized by parity-time (PT) symmetry. The proposed approach allows for the metamaterial-based interpretation and physical implementation of wave-objects (e.g., complex-source-points) and resonant states residing in complex-coordinate spaces.

Abstract
We introduce a complex-coordinate extension of the transformation-optics approach which enables for the generation and modeling of a general class of metamaterials with balanced loss and gain characterized by parity-time (PT) symmetry. The proposed approach allows for the metamaterial-based interpretation and physical implementation of wave-objects (e.g., complex-source-points) and resonant states residing in complex-coordinate spaces.File in questo prodotto:
