(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 ...

Stephen King’s Carrie, Professor X in X-Men and the Scarlet Witch in The Avengers are metaphorical expressions of the innate human desire to move things with the mind. A new study published on June 11 ...

Metasurfaces, as two-dimensional metamaterials, display fascinating ability in electromagnetic (EM) modulation within a sub-wavelength scale, opening up a new way for manipulating the properties of EM ...

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 ...

Fig. 1. The dielectric response models for conventional dielectric materials and for metamaterials. For conventional dielectric materials, there are three types of polarization models: Drude model for ...

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.

Stranger Things fans will be familiar with this scene: Eleven, a girl with telekinetic powers, stares intently at a Coke can. Without physically touching the can, she completely crushes it using her ...

Researchers have developed a general framework and metadevices for achieving dynamic control of THz wavefronts. Instead of locally controlling the individual meta-atoms in a THz metasurface (e.g., via ...

(Nanowerk Spotlight) Programmable metasurfaces have shown great potential for advanced electromagnetic wave manipulation in wireless communications, sensing, and other applications. However, a major ...
