Asymmetric Negative Refraction in Nonlocal Double-Wire Metamaterials
Tiago A. Morgado, Sylvain Lannebère, Enrico M. Renzi +2
We demonstrate that heterogeneous double-wire metamaterials, comprising two dissimilar and nonconnected wire arrays, enable loss-asymmetric hyperbolic dispersion and strongly asymm…
Chiral-Gain Photonics
Sylvain Lannebère, David E. Fernandes, Tiago A. Morgado +1
Here, we present an exploratory study of the potential applications of electrically biased materials that possess a nonreciprocal and non-Hermitian electromagnetic response analogo…
Non-Hermitian Linear Electrooptic Effect in 3D materials
Tiago A. Morgado, Tatiana G. Rappoport, Stepan S. Tsirkin +3
Here, we present an in-depth theoretical analysis of the linear electrooptic effect in low-symmetry three-dimensional (3D) conductive materials with large Berry curvature dipoles.…
Nonreciprocal and non-Hermitian material response inspired by semiconductor transistors
Sylvain Lannebère, David E. Fernandes, Tiago A. Morgado +1
Here, inspired by the operation of conventional semiconductor transistors, we introduce a novel class of bulk materials with nonreciprocal and non-Hermitian electromagnetic respons…
First Principles Homogenization of Periodic Metamaterials and Application to Wire Media
Sylvain Lannebère, Tiago A. Morgado, Mário G. Silveirinha
Here, we present an overview of a first principles homogenization theory of periodic metamaterials. It is shown that in a rather general context it is possible to formally introduc…
Topological pumping in photonic systems
Solange V. Silva, David E. Fernandes, Tiago A. Morgado +1
The topology of typical Chern insulators is rooted in the periodicity of the system along two directions of real-space. In this article, we depart from this standard concept and de…
Multiple Embedded Eigenstates in Nonlocal Plasmonic Nanostructures
Solange V. Silva, Tiago A. Morgado, Mario G. Silveirinha
Trapping light in open cavities is a long sought "holy grail" of nanophotonics. Plasmonic materials may offer a unique opportunity in this context, as they may fully suppress the r…
Drift-induced Unidirectional Graphene Plasmons
Tiago A. Morgado, Mário G. Silveirinha
Nonreciprocal photonic devices enable "one-way" light flows and are essential building blocks of optical systems. Here, we investigate an alternative paradigm to break reciprocity…
