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…
Non-Hermitian Linear Electro-Optic Effect Through Interactions of Free and Bound Charges
Sylvain Lannebère, Nader Engheta, Mário G. Silveirinha
In recent years, there has been growing interest in non-Hermitian phenomena in low-symmetry conductors, particularly optical gain driven by electro-optic effects. Conventional semi…
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…
A graphene inspired electromagnetic superlens
Sylvain Lannebère, Mário G. Silveirinha
In this paper we propose a new paradigm to create superlenses inspired by n-p-n junctions of graphene. We show that by adjoining a n-type region and a p-type region with a crystal…
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…
Photonic analogues of the Haldane and Kane-Mele models
Sylvain Lannebère, Mário G. Silveirinha
The condensed matter Haldane and Kane-Mele models revolutionized the understanding of what is an "insulator", as they unveiled novel classes of media that behave as metals near the…
Wave Instabilities and Unidirectional Light Flow in a Cavity with Rotating Walls
Sylvain Lannebère, Mário G. Silveirinha
We investigate the conditions for the emergence of wave instabilities in a vacuum cavity delimited by cylindrical metallic walls under rotation. It is shown that for a small vacuum…
Optical meta-atom for localization of light with quantized energy
Sylvain Lannebère, Mário G. Silveirinha
The capacity to confine light into a small region of space is of paramount importance in many areas of modern science. Here, we suggest a mechanism to store a quantized "bit" of li…
