Multifrequency optical invisibility with layered plasmonic scattering-cancellation cloaks: passive limits, higher-order multipoles, material realization, and experimental verification
Angular-momentum-biased magnetless nonreciprocity at terahertz and optical frequencies: modulation trade-offs, actuator-minimal integrated designs, and modeling beyond the omega_m much smaller than omega_1 coupled-mode approximation
Physically realizable unitary-efficiency wave-front transformation with gradient metasurfaces: extending the exact two-dimensional local-impedance theory to three-dimensional, polarization-coupled, and transmitting surfaces
Broadband and array-scale extensions of the parity-time-symmetric invisible acoustic sensor
Completing nanophotonic enhanced-circular-dichroism enantiomer sensing: single-molecule sensitivity, calibration-free background suppression, and site-specific chiral information
Experimental realization and loss-inclusive characterization of electrically tunable graphene-strip hyperbolic metasurfaces: topological transitions, extreme plasmon confinement, and spontaneous-emission enhancement
Disorder, loss, and bandwidth limits of polariton canalization at photonic magic angles in twisted α-MoO3 bilayers
