TL;DR: Two approaches are presented to achieve the possibility of miniaturized, potentially integrable, wave-based computing systems that are thinner than conventional lens-based optical signal and data processors by several orders of magnitude.

TL;DR: By applying the optical nanocircuit concepts to metasurfaces, an effective route to locally control light transmission over a deeply subwavelength scale is proposed, which may lead to large improvements in the manipulation of optical transmission and processing of nanoscale optical signals over conformal and Si-compatible substrates.

TL;DR: In this article, a subwavelength reconfigurable Huygens' metasurface realized by loading it with controllable active elements is presented, which offers unprecedented potentials for real-time, fast, and sophisticated electromagnetic wave manipulation such as dynamic holography, focusing, beam shaping/steering, imaging, and active emission control.

TL;DR: The planar metalens proposed empowers significant reduction in thickness, versatile focusing behavior, and high transmission efficiency simultaneously, showing a remarkable improvement compared with earlier ultrathin metasurface designs with less than 5% coupling efficiency.

TL;DR: In this article, a one-dimensional grating supporting a transverse magnetic mode with a BIC near 700 nm wavelength was studied and the existence of the BIC was verified using reflection measurements, which showed a vanishing reflection feature.
