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…

Engineering Topological Phases with a Traveling-Wave Spacetime Modulation

João C. Serra, Mário G. Silveirinha

Time-variant systems have recently garnered considerable attention due to their unique potentials in manipulating electromagnetic waves. Here, a novel class of topological spacetim…

Homogenization of Dispersive Spacetime Crystals: Anomalous Dispersion and Negative Stored Energy

João C. Serra, Mário G. Silveirinha

We introduce a homogenization approach to characterize the dynamical response of a generic dispersive spacetime crystal in the long-wavelength limit. The theory is applied to dispe…

Rotating Spacetime Modulation: Topological Phases and Spacetime Haldane Model

João C. Serra, Mário G. Silveirinha

Topological photonics has recently emerged as a very general framework for the design of unidirectional edge waveguides immune to back-scattering and deformations, as well as other…
