Harnessing the Terahertz Frontier: How Graphene Plasmonics is Unlocking Next-Generation Signal Processing

For decades, the terahertz (THz) region—spanning roughly from 0.1 to 10 THz—has remained one of the most tantalizing frontiers in science and engineering. It sits in the gap between electronics and photonics, too fast for traditional transistors yet too slow for most optical devices. Often called the “terahertz gap,” this spectral window holds transformative potential…
