Directional dependence of the plasmonic gain and nonreciprocity in drift-current biased graphene
Tiago A. Morgado, Mário G. Silveirinha
Here, we investigate the nonreciprocal propagation and amplification of surface plasmons in drift-current biased graphene, using both Galilean and relativistic-type Doppler shift t…
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…
Active graphene plasmonics with a drift-current bias
Tiago A. Morgado, Mário G. Silveirinha
We theoretically demonstrate that a system formed by a drift-current biased graphene sheet on a silicon carbide substrate enables loss compensation and plasmon amplification. The a…
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…
Nonlocal effects and enhanced nonreciprocity in current-driven graphene systems
Tiago A. Morgado, Mário G. Silveirinha
A graphene sheet biased with a drift electric current offers a tantalizing opportunity to attain unidirectional, backscattering-immune, and subwavelength light propagation, as prop…
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…
