Optical superoscillations are rapid, subwavelength spatial variations of the intensity and
phase of light, occurring in complex electromagnetic fields formed by the interference of …

As artificial 2D materials made of subwavelength inclusions, metasurfaces bear exotic
optical and electromagnetic properties not obtainable in naturally occurring materials. Based …

In this Letter, we experimentally report an achromatic metalens (AML) operating over a
continuous bandwidth in the visible. This is accomplished via dispersion engineering of …

Superoscillations are band-limited functions with the counterintuitive property that they can
vary arbitrarily faster than their fastest Fourier component, over arbitrarily long intervals …

During the last decade, new unusual physical phenomena have been discovered in
studying the optics of dielectric mesoscale particles of an arbitrary three-dimensional shape …

Label‐free super‐resolution (LFSR) imaging relies on light‐scattering processes in
nanoscale objects without a need for fluorescent (FL) staining required in super‐resolved FL …

Conventional optics is diffraction limited due to the cutoff of spatial frequency components,
and evanescent waves allow subdiffraction optics at the cost of complex near‐field …

Super-resolution (SR) microscopy has dramatically enhanced our understanding of
biological processes. However, scattering media in thick specimens severely limits the …

The resolution of conventional optical elements and systems has long been perceived to
satisfy the classic Rayleigh criterion. Paramount efforts have been made to develop different …
