Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

Metasurfaces, the ultrathin, 2D version of metamaterials, have recently attracted a surge of
attention for their capability to manipulate electromagnetic waves. Recent advances in …

A bi-isotropic Huygens' metasurface (BIHMS) is proposed for polarization-insensitive cross-
polarization conversion and wavefront manipulation, which can transmit and twist a linearly …

The strong optical chirality arising from certain synthetic metamaterials has important and
widespread applications in polarization optics, stereochemistry and spintronics. However …

In nature, the beetle Chrysina gloriosa derives its iridescence by selectively reflecting left-
handed circularly polarized light only. Here, an optical analogue is suggested based on an …

Active modulation of the polarization states of terahertz light is indispensable for polarization-
sensitive spectroscopy, having important applications such as non-contact Hall …

Chiral metasurfaces can achieve giant chiral optical responses and have been expanded
from the optical band to other electromagnetic bands. Here, we propose a new method for …

The chiral metasurface possesses wide applications in terahertz (THz) band. It is still an
important issue to control the chiral properties of metasuface by a simple and effective …

Polarization manipulations of electromagnetic waves can be obtained by chiral and
anisotropic metamaterials routinely, but the dynamic and high-efficiency modulations of …

Chirality, the absence of mirror symmetry, is predominant in nature. The chiral nature of the
electromagnetic field behaves differently with chiral matter for left circularly polarized and …
