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

Active plasmonics is a burgeoning and challenging subfield of plasmonics. It exploits the
active control of surface plasmon resonance. In this review, a first-ever in-depth description …

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

Metasurfaces, two-dimensional equivalents of metamaterials, are engineered surfaces
consisting of deep subwavelength features that have full control of the electromagnetic …

We report a dynamically tunable reflectarray metasurface that continuously modulates the
phase of reflected light in the near-infrared wavelength range under active electrical control …

In this paper, we will review both past and recent progresses in the generation, detection
and application of intense terahertz (THz) radiation. We will restrict the review to laser based …

Metamaterials, artificial electromagnetic media that are structured on the subwavelength
scale, were initially suggested for the negative-index'superlens'. Later metamaterials …
