A graphene-based terahertz metasurface provides linear-to-linear polarization conversion from 2.774 to 4.840 THz with a 54.27% relative bandwidth, and linear-to-circular conversion across 1.888–2.638 THz and 5.073–5.938 THz with relative bandwidths of 33.14% and 15.27%. Adjusting the graphene chemical potential dynamically controls conversion efficiency and axial ratio. Theoretical analysis, an admittance model, and resonant surface currents explain the mechanism, while structural-parameter and incidence-angle studies demonstrate broadband operation, high efficiency, and angular stability.

ResGatNet addresses the loss of ViT modulation-recognition robustness under low-SNR, time-varying noise by combining a large-kernel ResNet backbone, a gated CNN, and a Kolmogorov–Arnold Network (KAN). Large kernels expand local receptive fields, the gated module adaptively suppresses noise, and KAN strengthens global representation with lower parameter complexity. Experiments under quasi-static and time-varying noise show higher classification accuracy and generalization than the evaluated CNN and ViT baselines. The work was published in IEEE Access.

The research began as a 2023 university innovation training project and led to a paper in Diamond and Related Materials. Its flexible microwave structure combines a metallic resonator, vanadium-dioxide films, a graphene resistive layer, polyimide dielectrics, and a copper ground plane. The VO2 insulator-to-metal transition switches between polarization-conversion and absorption modes, while graphene sheet resistance tunes the response. The design exceeds 90% polarization conversion from 6.97 to 17.62 GHz at room temperature and 90% absorptivity from 13.33 to 19.47 GHz when VO2 is metallic.

A tunable bifunctional terahertz metasurface absorber based on vanadium dioxide and photoconductive silicon. Under one conductivity state, it exceeds 90% absorptivity across 2.47–3.71 THz and 8.90–10.62 THz, with relative bandwidths of 40.13% and 17.62%. Switching the VO2 state produces single-band absorption above 90% from 4.69 to 7.72 THz with a 48.83% relative bandwidth. Impedance matching, an equivalent transmission-line model, and electric-field distributions explain the mechanism, with the design retaining polarization-insensitive and wide-angle performance.

To meet the application demand for multiband and perfect absorbers, this paper presents a tri-band metasurface absorber composed of a patterned metal layer, an intermediate dielectric layer, and a metal ground plane. The absorber achieves absorption rates of 99.98%, 99.94%, and 99.98% at resonant frequencies of 5.16 GHz (C band), 7.27 GHz (C band), and 8.32 GHz (X band), respectively, enabling near-perfect absorption. Impedance-matching theory explains the formation of the three resonances, while simulated surface-current, electric-field, and magnetic-field distributions reveal the tri-band absorption mechanism. Changing the number of metal patterns on the top layer enables single-, dual-, and tri-band control. The dependence on polarization and incidence angles also demonstrates polarization insensitivity and wide-angle stability from 0 to 60 degrees. The proposed absorber is easy to design and lightweight, with potential applications in electromagnetic absorption, stealth, and sensing.
