The research team proposed a method called aberration-converged annular lithography (ACAL) system, as schematic diagram shown in Figure 1. The Gaussian beam is converted into a collimated annular beam ...

EurekAlert! - Metasurfaces, ultra-compact optical devices capable of "precisely manipulating light," have shown great potential in augmented reality (AR) glasses, holographic projection, biosensing, ...

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

Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to ...

The terahertz (THz) band of the electromagnetic spectrum holds immense promise for next-generation technologies, including high-speed wireless communication, advanced encryption, and medical imaging.

A chip smaller than one square millimeter stores 160 holographic images at arbitrary 3D coordinates, with each spatial ...

The mood at this year’s SPIE Advanced Lithography + Patterning Symposium was decidedly upbeat. The outlook for business is good, due in large measure to expectations of high demand for chips, driven ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...
