Optical vortex beams, characterized by their helical phase fronts and orbital angular momentum (OAM), are pivotal in applications such as high-capacity communication, optical manipulation, and quantum ...
In the realm of active 3D imaging, the light detection and ranging (LiDAR) technology plays a pivotal role, offering direct depth acquisition and robust resistance to environmental noises. LiDAR ...
The metasurface achieves two-dimensional beam scanning of ±45° at 5.2 GHz with a peak gain of 17.23 dBi while reducing radar visibility across five frequency bands. At 0.065 wavelengths thick, the ...
Holography-the science of recording and reconstructing light fields-has long been central to imaging, data storage, and encryption. Traditional holographic systems, however, rely on bulky optical ...
