Embedded eigenstates and virtual absorption using metamaterials (Conference Presentation)
Author(s): Alexandr E. Krasnok; Francesco Monticone; Andrea Alù

Paper Abstract

We discuss the possibility of confining electromagnetic energy and enhancing the interactions of light and matter in nanostructures, based on the concept of embedded eigenstates within the radiation continuum. We discuss how metasurfaces and metamaterials may be able to trap light in plain sight, and how lossless structures may be able to store energy in the transient by engaging complex zeros in the scattering response of the system. We also shed light on the role that reciprocity plays in the response of these systems, and how these functionalities may play a pivotal role in low-energy nanophotonic opto-electronic and bio-sensing devices.
