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 ...

A designer metamaterial has shown it can engineer emitted "blackbody" radiation with an efficiency beyond the natural limits imposed by the material’s temperature, a team of researchers report in ...

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 ...

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 ...
