Brain-computer interfaces (BCIs), invasive or non-invasive, have projected unparalleled vision and promise for assisting patients in need to better their interaction with the surroundings. Inspired by BCI-based rehabilitation technologies nerve-system impairments amputation, we propose an electromagnetic brain-computer-metasurface (EBCM) paradigm, regulated human's cognition brain signals directly non-invasively. We experimentally show that our EBCM platform can translate mind from evoked...
Abstract Metasurface holography has shown great potentials to reconstruct the full‐wave information of electromagnetic (EM) waves, bringing benefits high spatial resolution and good precision reconstructed images. To obtain higher security metasurface holography, orbital‐angular‐momentum (OAM) EM waves is taken into consideration as new freedom holography. The use two coding metasurfaces proposed achieve OAM‐encrypted One used generate different OAM beams with l = ±1 helical mode indices,...
Recent advances in digitally programmable metamaterials have accelerated the development of reconfigurable intelligent surfaces (RIS). However, excessive use active components (e.g., pin diodes and varactor diodes) leads to high costs, especially for those operating at millimeter-wave frequencies, impeding their large-scale deployments RIS. Here, we introduce an entirely different approach—moiré metasurfaces—to implement dynamic beamforming through mutual twists two closely stacked...
Abstract Metasurface holograms have the potential to be applied in a variety of practical fields. Here an anisotropic digital metasurface is proposed that can project polarization multiplexing patterns at microwave frequency, which modified Gerchberg–Saxton algorithm presented calculate phase masks. A 3‐bit coding metamaterial unit also proposed, capable independently manipulating transmission phases orthogonal linearly polarized electromagnetic waves. The influence wave‐front has been...
Abstract In the data‐driven society, fidelity and accuracy of automatic decisions behind scene rely fundamentally on a solid data or imaging acquisition system. However, conventional microwave imagers are inadequate relating to their resolution noise capability, mainly due limited aperture size rigid working principle. Here, programmable metasurface imager with high‐resolution anti‐interference performance is proposed. By implementing structure multilayer perceptron network in analog domain,...
Abstract The mumps resurgence has frequently been reported around the world in recent years, especially many counties vaccines have widely used. This study aimed to describe spatial epidemiological characteristics of Jiangsu, and provide a scientific basis for implementation adjustment strategies prevent control mumps. were described with ratio or proportion. Spatial autocorrelation, Tango's flexible scan statistics, Kulldorff's elliptic spatiotemporal statistics applied identify detect hot...
Background Polycystic ovary syndrome (PCOS) is the most common metabolic disorder and reproductive endocrine disease, posing an elevated risk to women of age. Although metabolism differences in serum, amniotic fluid urine have been documented PCOS, there remains a paucity evidence for vaginal fluid. This study aimed identify characteristics potential biomarkers PCOS Chinese Methods We involved ten newly diagnosed who attended gynecology at Zhongda Hospital matched them with healthy controls...
Metasurfaces have shown great potential in controlling the propagation of electromagnetic waves, making them suitable for holographic beam-shaping elements. Using principle array synthesis, holograms been realized microwave frequency to manipulate waves generate specific field patterns. However, current research is almost based on linear polarization and has little analysis circular hologram. Herein, we propose a hologram by sub-wavelength units with self-adaptively phase profiles waves. The...
