By carefully combining multiple structures, metamaterials can exhibit properties that don't naturally exist. Engineers now have a new, simpler way of making them, using a concept dubbed 'photonic doping'.
It turns out that after an appropriate teaching procedure even a relatively simple chemical system can perform non-trivial operations. In their most recent computer simulations researchers have shown that correctly programmed chemical matrices of oscillating droplets can recognize the shape of a sphere with great accuracy.
The new metamaterials can be fabricated in multiple layers to form complex, three-dimensional meta-atoms that reflect more light than shiny gold surfaces, usually considered the ultimate in infrared reflectivity.
Physicists have designed a handheld device inspired by the sonic screwdriver in Doctor Who and the tricorder in Star Trek that will use the power of MRI and mass spectrometry to perform a chemical analysis of objects.
