Controlling low-frequency broadband sound using compact structures remains a core challenge in acoustics. Achieving efficient, wideband sound absorption with lightweight, thin materials is vital for ...

(Nanowerk Spotlight) Radar technology has reached a point where it can detect the faintest electromagnetic signals, challenging even the most advanced stealth technologies. The evolution of radar ...

A recent study in Scientific Reports presented a graphene-based metamaterial as a solar absorber. The structure consisted of three layers: aluminum (Al) as the resonator, titanium nitride (TiN) as the ...

Researchers have developed the first fully-integrated, non-dispersive infrared (NDIR) gas sensor enabled by specially engineered synthetic materials known as metamaterials. The sensor has no moving ...

A recent article published in APL Materials defines metamaterials as artificial structures composed of subwavelength, atomic, or molecular-level components, possessing unique properties (such as ...
