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 …

The field of flexible antennas is witnessing an exponential growth due to the demand for
wearable devices, Internet of Things (IoT) framework, point of care devices, personalized …

Optical metasurfaces are starting to find their way into integrated devices, where they can
enhance and control the emission, modulation, dynamic shaping, and detection of light …

Reconfigurable reflective surfaces can alter the propagation environment to improve
wireless communication and power transfer. Paramount to this operation—which has …

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

Photonic time crystals are artificial materials whose electromagnetic properties are uniform
in space but periodically vary in time. The synthesis of these materials and experimental …

We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

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 …

Diverse electromagnetic (EM) responses of a programmable metasurface with a relatively
large scale have been investigated, where multiple functionalities are obtained on the same …
