Metamaterials with stiffness tunability have demonstrated great potential in mechanical systems that operate in variable environments. Real-time ...

Engineers used a process in which a laser instantly flashes metal powder into a fused solid. Using a common titanium alloy, engineers manufactured latticelike structures composed of hollow struts—each ...

(Nanowerk News) Metamaterials are artificially made materials that have certain patterns that change how light and matter interact. As a result, they have properties not found in nature. Researchers ...

Inspired by 3-D printing, researchers explored development of one mechanical property called effective static compressibility. As they now report, by using a single cartridge it's possible to print a ...

(Nanowerk News) Boston University researchers have developed a new, "intelligent" metamaterial – which costs less than ten dollars to build – that could revolutionize magnetic resonance imaging (MRI), ...

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 ...

In our increasingly noisy world, it can be hard to find some quiet time. Now, a team of mechanical engineers at Boston University has developed a new device that is specially designed to block up to ...

Although it is made of two thermally expanding materials, star-shaped unit cells of the metamaterial have a mechanical design that promotes negative thermal expansion (NTE) when heat is applied. The ...
