The terahertz band is, at least for now ... Measured THz power transmission of the metamaterial structures displaying fundamental resonances around 0.8 THz for the BPF and BSF (c).

Abstract: The terahertz (THz) metamaterial sensor represents an innovative technology designed to achieve superior sensitivity for trace detection by combining the advantages of THz spectroscopy and ...

A recent study published in Advanced Photonics Research investigated the effects of high-power terahertz (THz ... the study fabricated metamaterial-based band-pass and notch filters, which ...

The unit cell structure of this metamaterial comprises of two rectangular strips ... through photolithography and its performance is validated with a commercial terahertz time-domain spectrometer.

Credit: Surjadi et al, MIT The metamaterial's structure is so tiny that MIT's samples range from "several square microns to several square millimeters" across, according to the institute.

That's a real, er, stretch. But it's exactly what a team of researchers at MIT are claiming their new "strong but stretchy" metamaterial could enable. A metamaterial, in case you're wondering ...

Engineers have fabricated a metamaterial that is not only strong but also stretchy. Their new method could enable stretchable ceramics, glass, and metals, for tear-proof textiles or stretchy ...

The invention is a metamaterial, which is a material engineered to feature new and unusual properties that depend on the material's physical structure rather than its chemical composition.

But there's a trade-off: The stiffer a material, the less flexible it is. MIT engineers have now found a way to fabricate a metamaterial that is both strong and stretchy. The base material is ...
