Momentum considerations inside near-zero index materials
Michaël Lobet, Iñigo Liberal, Larissa Vertchenko +3
Near-zero-index (NZI) materials, i.e. materials having a phase refractive index close to zero, are known to enhance or inhibit light-matter interactions. Most theoretical derivatio…
Nonreciprocal ENZ-Dielectric Bilayers: Enhancement of Nonreciprocity from a Nonlinear Transparent Conducting Oxide Thin Film at Epsilon-Near-Zero (ENZ) Frequency
Diego M. Solís, Nader Engheta
We envision the use of an indium tin oxide (ITO) thin film as part of a bi-layered silicon-photonics subwavelength device to boost nonlinearity-assisted all-passive nonreciprocal b…
Temporal metamaterials with gain and loss
Victor Pacheco-Peña, Nader Engheta
Manipulation of wave-matter interactions in systems with loss and gain have opened new mechanisms to control wave propagation at will. Metamaterials and metasurfaces having spatial…
Static-to-dynamic field conversion with time-varying media
Mario Junior Mencagli, Dimitrios L. Sounas, Mathias Fink +1
In this Letter, we theoretically demonstrate that a uniform static electric field distribution can be partially converted to radiation fields when a portion of the medium undergoes…
Spatiotemporal Isotropic-to-Anisotropic Meta-Atoms
Victor Pacheco-Peña, Nader Engheta
Metamaterials and metasurfaces are designed by periodically arranged subwavelength geometries, allowing a tailored manipulation of the electromagnetic response of matter. Here, we…
Nonreciprocal guided waves in presence of swift electron beams
Asma Fallah, Yasaman Kiasat, Mário G. Silveirinha +1
Breaking the reciprocity of electromagnetic interactions is of paramount importance in photonic and microwave technologies, as it enables unidirectional power flows and other uniqu…
