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

Plasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-
based metamaterials, have attracted progressively increasing attention in recent years …

As a unique phase transition material, vanadium dioxide (VO 2) has been widely applied in
switchable and modulating metasurfaces. In this work, VO 2-based reflective meta-atoms are …

Multiple antenna technologies have attracted much research interest for several decades
and have gradually made their way into mainstream communication systems. Two main …

The use of large arrays might be the solution to the capacity problems in wireless
communications. The signal-to-noise ratio (SNR) grows linearly with the number of array …

Intelligence at either the material or metamaterial level is a goal that researchers have been
pursuing. From passive to active, metasurfaces have been developed to be programmable …

Intelligent metasurfaces have gained significant importance in recent years due to their
ability to dynamically manipulate electromagnetic (EM) waves. Their multifunctional …

Virtual reality (VR) and augmented reality (AR) have found widespread applications in
education, engineering, healthcare, and entertainment. However, these near-eye displays …

Active metasurfaces enable dynamic manipulation of the scattered electromagnetic
wavefront by spatially varying the phase and amplitude across arrays of subwavelength …

Chromatic aberration-free meta-devices (eg, achromatic meta-devices and abnormal
chromatic meta-devices) play an essential role in modern science and technology. However …
