Structural colors traditionally refer to colors arising from the interaction of light with structures
with periodicities on the order of the wavelength. Recently, the definition has been …

Chiral metamaterial absorbers (CMMAs), a particular class of chiral metamaterials that
refuse the transmission of incident radiation and exhibit different optical responses upon …

Chirality refers to a geometric phenomenon in which objects are not superimposable on
their mirror image. Structures made of nanoscale chiral elements can exhibit chiroptical …

Enhancing the circular dichroism signals of chiral plasmonic nanostructures is vital for
realizing miniaturized functional chiroptical devices, such as ultrathin wave plates and high …

Here we demonstrate a novel anti-counterfeiting method, 3D chiral color printing, which
displays a plasmonic color print under left-handed circular polarized (LCP) light, while …

Optically active achiral metasurfaces offer a promising way to detect chiral molecules based
on chiroptic methods. The combination of plasmon-enhanced circular dichroism (CD) and …

Non-Hermitian optical metasurfaces have recently attracted interest as a platform for
controlling light in amplitude, phase, and polarization. Here we predict that breaking parity …

In this article, a novel polarization‐dependent metasurface (PDMS) structure is presented
and applied to realize a wideband high‐gain antenna with multiple resonances. The PDMS …

2D black phosphorus (BP) possesses an in‐plane anisotropy, offering another degree of
freedom to create new optoelectronic and photonic devices, such as waveplates with atomic …

Perfect absorbers play crucial roles in optical functional devices. Among various types of
absorbers, moth-eye structures are known for their excellent absorbing efficiency. In this …
