Multi-Person 2-D Positioning Method Based on 77 GHz FMCW Radar
Micromachines, 2023 As the world’s population ages, technologies that enable long-term non-contact monitoring of patients are of great research significance. For this purpose, we propose a multi-person 2-D positioning method based on a 77 GHz FMCW radar.

Luminosity scans for beam diagnostics [PDF]
Physical Review Accelerators and Beams, 2018 A new type of fast luminosity separation scans ("Emittance Scans") was introduced at the CERN Large Hadron Collider (LHC) in 2015. The scans were performed systematically in every fill with full-intensity beams in physics production conditions at the Interaction Point (IP) of the Compact Muon Solenoid (CMS) experiment.

Golden beam data for proton pencil-beam scanning [PDF]
Physics in Medicine and Biology, 2012 Proton, as well as other ion, beams applied by electro-magnetic deflection in pencil-beam scanning (PBS) are minimally perturbed and thus can be quantified a priori by their fundamental interactions in a medium. This a priori quantification permits an optimal reduction of characterizing measurements on a particular PBS delivery system.

Ultrathin Dual‐Band Wide‐Angle Beam Scanning Metalens Based on High‐Efficiency Meta‐Atom
Advanced Photonics Research, 2022 Metasurfaces composed of planar subwavelength‐scaled meta‐atoms demonstrate unprecedented wavefront manipulation capabilities. However, the wavelength‐dependent property of the metasurface could severely reduce the design freedom, and most metasurfaces ...
