Nonreciprocal-Beamsteering Reflective Metasurface
, 2021 This study proposes a reflective metasurface for full-duplex nonreciprocal-beam-steering and amplification. The metasurface is realized by leveraging the exotic characteristics of novel interconnected meta-atoms providing three main functions ...

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Metasurface- and PCSEL-Based Structured Light for Monocular Depth Perception and Facial Recognition
The novel depth-sensing system presented here revolutionizes structured light (SL) technology by employing metasurfaces and photonic crystal surface-emitting lasers (PCSELs) for efficient facial recognition in monocular depth-sensing. Unlike conventional

A Metasurface Superstrate for Mutual Coupling Reduction of Large Antenna Arrays
IEEE Access, 2020 In this paper, a ε-negative metasurface superstrate is proposed for mutual coupling reduction of large antenna arrays. Unlike the previous decoupling metasurface works that are mostly confined to two-ports antennas, the proposed decoupling ...

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption
Advanced Optical Materials, EarlyView.ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.
