THE spinning electron of Uhlenbeck and l Goudsmit has brilliantly filled up a serious gap in atomic physics, but, while we cannot withhold our admiration from its successes, it is only fair to ...

Researchers have developed a novel metasurface-based method to generate terahertz complex vector light fields using surface ...

This paper proposes a general method for designing ultra-compact on-chip optical devices that can efficiently generate pre-designed complex wavefront vector beams (VOFs) under surface wave (SW ...
