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 ...

A new programmable metasurface performs dynamic beamforming and radar cross-section reduction across five frequency bands in ...

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the ...

Researchers have developed a single metasurface that can effectively tune the different properties of laser light, including wavelength, without the need of additional optical components. The ...

The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.

(Nanowerk News) Reconfigurable metasurfaces are transforming wireless communication by adjusting electromagnetic (EM) wave characteristics such as amplitude, phase, and polarization. These planar ...

Researchers from Jinan University, under the direction of Professor Yanjun Bao and Baojun Li, developed a novel metasurface-based imaging method that allows for the simultaneous measurement of ...

Like soft serve ice cream, beams of atoms and molecules now come with a swirl. Vortex beams made of light or electrons have shown promise for making special types of microscope images and for ...

Physicists in China have demonstrated that a structure called an optical metasurface can individually trap up to 78,400 ...
