Giant and Broadband THz and IR Emission in Drift-biased Graphene-Based Hyperbolic Nanostructures
L. Wang, N. K. Paul, J. Hihath +1
We demonstrate that Cherenkov radiation can be manipulated in terms of operation frequency, bandwidth, and efficiency by simultaneously controlling the properties of drifting elect…
Lateral recoil optical forces on nanoparticles near nonreciprocal surfaces
N. K. Paul, J. S. Gomez-Diaz
We investigate lateral recoil forces exerted on nanoparticles located near plasmonic platforms with in-plane nonreciprocal response. To this purpose, we first develop a comprehensi…
Low-Power Optical Traps using Anisotropic Metasurfaces: Asymmetric Potential Barriers and Broadband Response
Nayan K. Paul, J. Sebastian Gomez-Diaz
We propose the optical trapping of Rayleigh particles using tailored anisotropic and hyperbolic metasurfaces illuminated with a linearly polarized Gaussian beam. This platform perm…
Giant Lateral Optical Forces on Rayleigh Particles near Hyperbolic and Extremely Anisotropic Metasurfaces
N. K. Paul, D. Correas-Serrano, J. S. Gomez-Diaz
We report a dramatic enhancement of the lateral optical forces induced on electrically polarizable Rayleigh particles near hyperbolic and extremely anisotropic metasurfaces under s…
