Abstract: A device for producing a subwavelength hologram. The device comprises a metasurface layer attached to a substrate. The metasurface layer includes an array of plasmonic antennas that simultaneously encode both wavelength and phase information of light directed through the array to produce a hologram. The wavelength is determined by the size of the antennas, and the phase is determined by the orientation of the antennas.

Abstract: A system including a first cylindrical structure embedded into a second cylindrical structure. The first cylindrical structure includes a combustion chamber. The first cylinder additionally includes a plurality of plasmonic materials on an outer wall of the first cylindrical structure. The second cylindrical structure includes a plurality of photovoltaic cells on an inner wall of the second cylindrical structure. A radius of the second cylindrical structure is greater than a radius of the first cylindrical structure.
