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

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 …

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 …

Relying on abrupt phase discontinuities, metasurfaces characterized by a transversely
inhomogeneous surface impedance profile have been recently explored as an ultrathin …

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

Traditionally,“metamaterials” have been described by effective medium parameters due to
the subwavelength nature of unit particles. The continuous nature of medium parameters …

We propose all‐dielectric metasurfaces that can be actively re‐configured using the phase‐
change material Ge2Sb2Te5 (GST) alloy. With selectively controlled phase transitions on …

Metasurfaces, composed of 2-D planar arrays of sub-wavelength metallic or dielectric
scatterers, have provided unprecedented freedoms in manipulating electromagnetic (EM) …

Surface plasmon polaritons (SPPs) are highly localized surface waves that exist on the
interface of two media with opposite permittivities at optical frequencies. To produce spoof …

We propose to realize ultra-wideband polarization conversion metasurfaces in microwave
regime through multiple plasmon resonances. An ultra-wideband polarization conversion …
