  • (Left) A schematic of a directional terahertz wireless link that incorporates two bounces off of walls, so that there is no line-of-sight path from the transmitter to the receiver. The inset shows the bit error rate (BER) on a log scale, as a function of the output power of the transmitter. At both 100 GHz and 200 GHz, essentially error free transmission (BER = 10^-9) can be achieved. (Right) a close-up photo of the transmitter rig used in these measurements, which include a horn antenna and a Teflon lens to increase the gain of the system.
