When light hits certain molecules, it dislodges electrons and creates areas of positive and negative charge. An X-ray free-electron laser study has directly observed how this charge transfer affects a molecule’s structure for the first time.

Detecting, Exploiting Non-Line-of-Sight Paths for Terahertz Signals in Wireless Communications
After developing a link discovery method in 2020 using terahertz radiation, Rice and Brown researchers addressed what would happen if a wall or other reflector creates a non-line-of-sight path from the base station to the receiver. In APL Photonics, they consider two different generic types of transmitters and explore how their characteristics can be used to determine whether an NLOS path contributes to the signal received by the receiver.
