This paper presents a reconfigurable polarization converter employing a metasurface with
liquid crystals (LC) to convert linearly polarized (LP) waves into either left-hand circularly …

In this paper, an ultrathin Huygens' metasurface is designed for generating an orbital
angular momentum (OAM) beam. The Huygens' metasurface is a double-layered metallic …

Metasurfaces with linear phase gradients can redirect light beams. Controlling both phase
and amplitude of a metasurface is proposed to extend Snell's law to the realm of complex …

In this paper, a total of 4770 effective documents about metamaterial absorbers were
retrieved from the Web of Science Core Collection database. We scientifically analyzed the …

Holographic displays offer a method to completely reconstruct any desired wavefront and
can thus lead to breakthrough innovation in beamforming, sensing, and information …

Beginning with Fermat's principle, we provide a detailed derivation of the generalized laws
of refraction and reflection for a geometry realizing a metasurface. We first solve the Euler …

Most of the existing metasurfaces are effective for the incident wave with the specific
circularly polarized (CP) or linearly polarized (LP) state, that is the polarization-sensitive …

Line waves (LWs) refer to confined edge modes that propagate along the interface of dual
electromagnetic metasurfaces while maintaining mirror reflection symmetries. Previous …

Flat optics have been proposed as an attractive approach for the implementation of new
imaging and sensing modalities to replace and augment refractive optics. However …
