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

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 …

Next-generation cellular technologies, commonly referred to as the sixth generation (6G),
are envisioned to support a higher system capacity, better performance, and network …

Metasurfaces are a topic of significant research and are used in various applications due to
their unique ability to manipulate electromagnetic waves in microwave and optical …

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

This paper presents design and analysis methods for planar antennas based on modulated
metasurfaces (MTSs). These antennas operate on an interaction between a cylindrical …

Here, we explain the principles of operating lens antennas, and discuss their potential
application for future 5G communications systems. We discuss the connection between the …

Wireless communications and sensing have notably advanced thanks to the recent
developments in both software and hardware. Although various modulation schemes have …

Based on a transformation optics method, a flat compact dual-polarized Luneburg lens
antenna is proposed and implemented using the printed-circuit-board-stacked gradient …

The introduction of electromagnetic (EM) media with unique field manipulation properties,
