Gesture-controlled reconfigurable metasurface system based on surface electromyography for real-time electromagnetic wave manipulation.

Gesture recognition plays a significant role in human-machine interaction (HMI) system. This paper proposes a gesture-controlled reconfigurable metasurface system based on surface electromyography (sEMG) for real-time beam deflection and polarization conversion. By recognizing the sEMG signals of user gestures through a pre-trained convolutional neural network (CNN) model, the system dynamically modulates the metasurface, enabling precise control of the deflection direction and polarization state of electromagnetic waves.

Auto-collimation diffraction of two-dimensional metal-dielectric grating with azimuth angle of 45°.

Grating under auto-collimation configuration with polarization-independent high diffraction efficiency plays an important role in the displacement measurement system, spectral beam combining system and so on. In this paper, we proposed, for the first time, a reflective two-dimensional metal-dielectric grating of which the (-1, -1) order beam is diffracted back along the input light direction, when the incident azimuth angle is 45°. With optimized structure, the (-1, -1) order diffraction efficiencies of transverse electric polarization (TE) and transverse magnetic polarization (TM) are 95.

Metacavities by harnessing the linear-crossing metamaterials.

The formed optical cavity mode intensively relies on the size and geometry of optical cavity. When the defect or impurity exists inside the cavity, the formed cavity mode will be destroyed. Here, we propose a metacavity consisting of arrays of linear-crossing metamaterials (LCMMs) with abnormal dispersion, where each LCMM offers both the directional propagation channel for all incident angles and the negative refraction across its neighboring LCMMs.

Measuring high-efficiency perfect composite vortex beams with reflective metasurfaces in microwave band.

Origins and conservation of topological polarization defects in resonant photonic-crystal diffraction.

We present a continuative definition of topological charge to depict the polarization defects on any resonant diffraction orders in photonic crystal slab regardless they are radiative or evanescent. By using such a generalized definition, we investigate the origins and conservation of polarization defects across the whole Brillouin zone. We found that the mode crossings due to Brillouin zone folding contribute to the emergence of polarization defects in the entire Brillouin zone.

F-FDG PET/CT findings in a mucosa-associated lymphoid tissue lymphoma patient coexisting with primary myelofibrosis.

The role of light in regulating plant growth, development and sugar metabolism: a review.

Light provides the necessary energy for plant photosynthesis, which allows plants to produce organic matter and energy conversion, during plant growth and development. Light provides material energy to plants as the basis for cell division and differentiation, chlorophyll synthesis, tissue growth and stomatal movement, and light intensity, photoperiod, and light quality play important roles in these processes. There are several regulatory mechanisms involved in sugar metabolism in plants, and light, as one of the regulatory factors, affects cell wall composition, starch granules, sucrose synthesis, and vascular bundle formation.
