Controlling the sign of chromatic dispersion in diffractive optics (2017, neutral): “Metasurfaces have attracted great interest in the recent years [3 – 12] because they enable precise control of optical wavefronts and are easy to fabricate with conventional microfabrication technology in a flat, thin, and lightweight form factor.”
Wireless Networks Design in the Era of Deep Learning: Model-Based, AI-Based, or Both? (2019, background): “Also, they constitute a suitable distributed platform to perform low-energy and low-complexity sensing [55], storage [56], and analog computing [57].”
A review of gap-surface plasmon metasurfaces: fundamentals and applications (2018, methodology): “Motivated by the theoretical work [185], the first metasurface that allows for mathematical operations on visible light was demonstrated using GSPM working in a reflection setup (left panel of Figure 12A) [187].”
Nonlocal flat optics (2022, methodology): “Indeed, nonlocal metasurfaces may perform, in principle, all the processing operations of Fourier optics, but in the form of a single, compact, optical element [25],[42].”
