Scattering from spheres made of time-varying and dispersive materials
G. Ptitcyn, A. G. Lamprianidis, T. Karamanos +8
Exploring the interaction of light with time-varying media is an intellectual challenge that, in addition to fundamental aspects, provides a pathway to multiple promising applicati…
Giant asymmetric second-harmonic generation in bianisotropic metasurfaces based on bound states in the continuum
Ehsan Mobini, Rasoul Alaee, Robert W. Boyd +1
Bianisotropy is a powerful concept enabling asymmetric optical response, including asymmetric reflection, absorption, optical forces, light trapping, and lasing. The physical origi…
Kelvin's Chirality of Optical Beams
Sergey Nechayev, Jörg S. Eismann, Rasoul Alaee +3
Geometrical chirality is a property of objects that describes three-dimensional mirror-symmetry violation and therefore it requires a non-vanishing spatial extent. In contrary, opt…
Superscattering, Superabsorption, and Nonreciprocity in Nonlinear Antennas
Lin Cheng, Rasoul Alaee, Akbar Safari +3
We propose tunable nonlinear antennas based on an epsilon-near-zero material with a large optical nonlinearity. We show that the absorption and scattering cross sections of the ant…
Kerker Effect, Superscattering, and Scattering Dark State in Atomic Antennas
Rasoul Alaee, Akbar Safari, Vahid Sandoghdar +1
We study scattering phenomena such as the Kerker effect, superscattering, and scattering dark states in a subwavelength atomic antenna consisting of atoms with only electric dipole…
Dynamic coherent perfect absorption in nonlinear metasurfaces
Rasoul Alaee, Yaswant Vaddi, Robert W. Boyd
We propose a tunable coherent perfect absorber based on ultrathin nonlinear metasurfaces. The nonlinear metasurface is made of plasmonic nanoantennas coupled to an epsilon-near-zer…
