Generalized Time-Varying Drude Model for Dispersive and Lossy Modulations
Antonio Ganfornina-Andrades, J. Enrique Vázquez-Lozano, Iñigo Liberal +1
We develop a generalization of the time-varying Drude model, treating carrier density, effective mass, and collision rate as explicit functions of time. We derive expressions for p…
Synthetic crystal rotation with spacetime metamaterials
Iñigo Liberal, Alejandro Manjavacas
The interaction of light with rotating bodies has been historically limited to rotation frequencies much smaller than optical frequencies. Here, we investigate synthetic crystal ro…
Generalized Epsilon-Near-Zero Polaritons on Uniaxial Metasurfaces
Francisco Javier Alfaro-Mozaz, Iñigo Liberal
Epsilon-near-zero (ENZ) thin films facilitate strong light-matter interactions with a widespread impact in nonlinear, quantum and thermal photonics. Here, we extend the scope of th…
Mirrors without spatial boundaries
J. Enrique Vázquez-Lozano, Victor Pacheco-Peña, Iñigo Liberal
Mirrors are one of the most elementary and ubiquitous components of optical systems. They use a sharp refractive index contrast to provide the basic capability of reflecting light.…
