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.

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 ...

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.

(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 ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2023.230025 discusses near-eye display based on metasurface devices. With the rise of the meta-universe, virtual reality (VR) and ...

(Nanowerk Spotlight) As our digital devices handle increasingly complex computations, scientists have looked to physics for inspiration on new computing paradigms. Rather than shuttling electrical ...
