Over the past few decades, metasurfaces have revolutionized conventional bulky optics by providing an effective approach to manipulate optical waves at the subwavelength scale. This advancement holds great potential for compact, multifunctional, and reconfigurable optical devices. Notably, metasurfaces constru...
metasurface composed of cross-shaped resonators has been proposed to control the polarization states of reflected waves under linearly polarized incidence by varying the incident angle, as illustrated in Fig.3(f) to (h) [90]. The cross-shaped resonator exhibits a magnetic resonance at 0.54 THz,...
Phase-change-driven dielectric-plasmonic transitions in chalcogenide metasurfaces Phase change materials are of enormous interest in the field of plasmonics and nanophotonics. For such applications, it has gone largely unnoticed that some chalcogenides accrue plasmonic properties in the transition from an ...
Optical metasurfaces (OMs) have emerged as promising candidates to solve the bottleneck of bulky optical elements. OMs offer a fundamentally new method of light manipulation based on scattering from resonant nanostructures rather than conventional refraction and propagation, thus offering efficient phase, ...
The dynamic meta-hologram may be produced at an incredibly high frame rate (9523 frames per second) in the visible region by properly coding the digital micro-mirror device according to different parts of the metasurface. Multiplexing meta-holograms leverage a range of degrees of freedom, ...
Computing metasurfaces are two-dimensional artificial nanostructures capable of performing mathematical operations on the input electromagnetic field, including its amplitude, phase, polarization, and frequency distributions. Rapid progress in the develo
