Query: Accelerating Light with Metasurfaces   It has been recently shown that especially engineered light beams have the
remarkable ability to propagate along curved trajectories in vacuum. Current
methods for generating accelerating beams use phase modulators and lenses
leading to length scales on the order of tens of centimeters or larger. This
poses constraints and severely limits their applicability inside materials.
Here, we accelerate light inside glass using a metasurface consisting of
plasmonic nanoantennas. Highly-bending beams with radii of curvature on the
order of a hundred microns were generated, and the imaged intensities agree
well with theory. Our approach for generating accelerating beams allows for
their integration into on-chip photonic systems.
