Artist鈥檚 impression of silica鈥揼old nanoparticles acting as 鈥渓ight concentrators鈥�, focusing energy into tiny hotspots to boost terahertz emission. The effect was studied using ultrafast laser pulses. Image generated by Dr Vittorio Cecconi using Adobe Firefly.

Tiny 鈥榣ight-concentrating鈥� particles boost terahertz technology, study shows

Scientists have found a way to boost terahertz technology using particles thousands of times smaller than a grain of sand.
