The photonic spin Hall effect (SHE) refers to the transverse spin separation of photons with
opposite spin angular momentum, after the beam passes through an optical interface or …

Metasurfaces are ultrathin metamaterials consisting of planar electromagnetic (EM)
microstructures (eg, meta-atoms) with pre-determined EM responses arranged in specific …

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

The refractive-lens technique has been well developed over a long period of evolution,
offering powerful imaging functionalities, such as microscopes, telescopes, and …

Janus monolayers, a class of two‐faced 2D materials, have received significant attention in
electronics, due to their unusual conduction properties stemming from their inherent out‐of …

Recent advances in artificial subwavelength structures promise the realization of ultrathin,
lightweight, and flat metalens, providing a potential candidate for traditional bulky and …

In the past centuries, the scale of engineering optics has evolved toward two opposite
directions: one is represented by giant telescopes with apertures larger than tens of meters …

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

Traditional technologies to generate and manipulate the orbital angular momentum (OAM)
suffer from bulky size and do not lend themselves to nanophotonic systems. An ultrathin …

The geometric phase concept has profound implications in many branches of physics, from
condensed matter physics to quantum systems. Although geometric phase has a long …
