The growing maturity of nanofabrication has ushered massive sophisticated optical
structures available on a photonic chip. The integration of subwavelength-structured …

In undergraduate courses on classical electromagnetism, it is taught that a perfect conductor
expels the electromagnetic (EM) field, and hence its surface is not able to support the …

A composite gradient-index metasurface (C-GM) array for microwave power reception
(MPR) operating at 5.8 GHz center frequency was introduced. The array is insensitive to the …

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

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

In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

Metasurfaces are planar metamaterials exhibiting certain inhomogeneous phase
distributions for transmitted or reflected waves, which can efficiently reshape the wave‐fronts …

Research on two-dimensional designer optical structures, or metasurfaces, has mainly
focused on controlling the wavefronts of light propagating in free space. Here, we show that …

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

Surface plasmons (SPs) are electromagnetic surface waves that propagate at the interface
between a conductor and a dielectric. Due to their unique ability to concentrate light on two …
