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.

The ability to precisely control the various properties of laser light is critical to much of the technology that we use today, from commercial virtual reality (VR) headsets to microscopic imaging for ...

Traditionally, active metasurface researches have primarily focused on changing the dielectric constant and permeability of the substrate, which frequently results in resonance effect and ohmic loss.

The Stanford team created a metasurface from a polymer previously used in solar panels and printable electronics. They found ...

(Nanowerk News) The orbital angular momentum (OAM) of electromagnetic waves — a kind of “structured light” — is associated with a helical or twisted wavefront. The helical modes are characterized by a ...

Ultrasonic beams fired through a 3D-printed metasurface can create localized pockets of sound that are inaudible to ...

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 ...
