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…
Fresnel Drag in the Homogenization Limit with Space-Time-Modulated Wire Media
A. B. Yakovlev, M. G. Silveirinha, A. Pal +1
Space-time modulations of the electromagnetic response offer new opportunities for wave control. In particular, such systems can emulate moving-medium responses and the associated…
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…
Symmetry-Based Classification of Chern Phases in Honeycomb Photonic Crystals
Rodrigo P. Câmara, Tatiana G. Rappoport, Mário G. Silveirinha
In this work, we develop a symmetry-based classification of Chern phases in honeycomb photonic crystals, considering arbitrary nonreciprocal couplings compatible with energy conser…
Influence of Spatial Dispersion in the Topological Edge States of Magnetized Plasmas
João C. Serra, Mário G. Silveirinha
Conventional Chern insulators are two-dimensional periodic structures that support unidirectional edge states at the boundary, while the wave propagation in the bulk regions is for…
Gain-Momentum Locking in Chiral-Gain Media
João C. Serra, Nader Engheta, Mário G. Silveirinha
Conventional optical materials are characterized by either a dissipative response, which results in polarization-independent absorption, or by a gain response that leads to wave am…
