Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

Conventionally, active metasurface scientists have mainly concentrated on altering the dielectric constant and permeability of the substrate, which usually leads to resonance effect and ohmic loss.

(Nanowerk News) Researchers described a new strategy of designing metamolecules that incorporates two independently controllable subwavelength meta-atoms. This two-parametric control of the ...

Figure 1: Typical applications of metasurfaces in wireless communication include: RIS (Reconfigurable Intelligent Surface-based Wireless Relay Systems), Digit (Digital-Coded Metasurface-Based ...

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 ...

Harnessing the power of 'phase-change' materials, researchers have demonstrated how reconfigurable metasurfaces -- artificial materials with extraordinary optical properties -- are crucial to the ...

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.

In particular, the active metasurface is regarded as a technology with a wide range of applications due to its tunable optical characteristics with an electrical signal. However, the previous active ...
