Recently, the growing interest in reconfigurable intelligent surface (RIS) technology has spurred extensive research on its utilization terahertz (THz) regime. The reconfiguration of THz field empowered by RIS holds great significance for various practical RIS-aided implementations at frequencies. In this study, we present a multi-bit liquid crystal-based that allows programmable control waves. proposed is characterized an achievable 3-bit working state as well near 270° maximum phase shift...
Coding metasurfaces have emerged as a promising venue for terahertz (THz) beam steering and beamforming. In this study, we designed transmission metasurface with complementary structure based on Babinet's principle. The beam-steering capability of the coding is implemented by encoding “0” “1” elements different phase responses controlling sequences. deflection angle can be controlled changing period these 0 1 elements. Despite development technology, measurements direction pattern steered...
Resonant antennas have garnered considerable interest in terahertz and visible regimes owing to its extraordinary localized field concentration capability. In this work, we experimentally demonstrate a novel metal-free detector, which is fashioned by heavily doped polysilicon using standard CMOS process. The computational results show that the incident can be largely enhanced within antenna gap area at resonance of 650 GHz. room temperature measured responsivity noise equivalence power...
Phase-only holograms (POHs) are often generated by the Gerchberg–Saxton (GS) algorithm. Nevertheless, low-quality reconstruction and iterative divergence plague traditional GS method, reducing quality of holographic display. Noise still affects adaptive weighted (AWGS) algorithms, despite their ability to ensure convergence through addition planned feedback. We propose an optimized AWGS algorithm, named weighting constraints (OAWGS), for generation POHs high-quality The contrast intensity...
This paper presents a polarization reconfigurable antenna based on liquid crystal (LC) operating at around 14 GHz in the Ku-band. The consists of two orthogonally-positioned defected ground structure (DGS) phase shifters loaded with LC together square radiating patch. By adjusting permittivity LC, DGS can induce delays 0°, +90° and -90° to orthogonal modes. allows for reconfiguration states radiated far field from linear right/left-handed circularly polarized state, correspondingly. proposed...
