So far, the environment has been considered as a source of fading, clutter, and blockage,
with detrimental consequences for efficiency and robustness of communication systems …

The terahertz region is a special region of the electromagnetic spectrum that incorporates
the advantages of both microwaves and infrared light waves. In the past decade …

Optical metasurfaces are thin‐layer subwavelength‐patterned structures that interact
strongly with light. Metasurfaces have become the subject of several rapidly growing areas …

Digital phase shifters have been applied in traditional phased array antennas to realize
beam steering. However, the phase shifter deals with the phase of the induced current; …

The field of metamaterials has opened landscapes of possibilities in basic science, and a
paradigm shift in the way we think about and design emergent material properties. In many …

A general design paradigm for a novel type of acoustic metasurface is proposed by
introducing periodically repeated supercells on a rigid thin plate, where each supercell …
