Abstract Terahertz (THz) technologies have become a focus of research in recent years due to their prominent role envisioned future communication and sensing systems. One the key challenges facing field is need for tools enable agile engineering THz wave fronts. Here, we describe reconfigurable metasurface based on GaN technology with an array-of-subarrays architecture. This subwavelength-spaced array, under control 1-bit digital coding sequence, can switch between enormous range possible...
Integrated metasurfaces with diversified functionalities have demonstrated promising prospects for comprehensive implementations in compact 5G/6G communication systems by flexibly manipulating electromagnetic (EM) waves. Increasingly emerged multifunctional successfully revealed integrated wavefront manipulations via phase gradient arrays, coding apertures, independent polarization control, asymmetric transmission/reflection, etc. However, more degrees of freedom terms multi-band/broadband...
Abstract Boasting superior flexibility in beam manipulation and a simpler framework than traditional phased arrays, terahertz metasurface-based arrays show great promise for 5G-A/6G communication networks. Compared with the reflective reconfigurable intelligent surface (reflective RIS), transmissive RIS (TRIS) offers more feasibility transceiver multiplexing systems to meet growing demand high-performance tracking radar systems. However, TRIS encounters greater challenges phase shift,...

A metasurface composed of multiple resonator arrangements with a certain phase distribution is capable efficient wavefront manipulation. An anisotropic matrix consisting asymmetric metal cross particles near-field coupling-induced achieves simultaneous distinctive dualpolarization anomalous reflections. Using polarization splitting, due to the gradients subunit, x-and-y-polarization components incident terahertz waves can be efficiently deflected different deflection angles in single plane...
Terahertz reconfigurable intelligent surfaces (RIS) stand out from conventional phased arrays thanks to their unique electromagnetic properties and interconnect paradigms. They are a vital technology for terahertz wireless communication radar detection systems. Compared with 1-bit coding metasurfaces, 2-bit metasurfaces offer significant advantages such as single beam steering reduced quantization errors. Electrically controlled switchable have been restricted by the switch performance...
Coding metasurfaces have drawn great attention for its digital wave manipulation in deep subwavelength-scale the last decade, more sophisticated and flexible coding strategies suitable terahertz wavefront manipulations are becoming urgently demanded. Due to rigidity phase gradient division, both conventional technique lack flexibility expand applications a large field of view accurate targeting. This study presents generalized method by precisely reconfiguring array factor based on phased...
Polarization manipulation plays a pivotal role in integrated multifunctional devices. Various metasurface-based polarization converters successfully demonstrated high efficiency and broad bandwidth. However, new mechanisms to aggressively enhance performance are still dire need. Here, theoretical experimental evidence corroborates an efficient ultrawideband transmissive converter based on topological design method. The triple-layer meta-device consists of layer anisotropic zigzag-split...
