Ångström Lecture 2018: Twisted Light and Radio Waves
Twisted light ( sv. "skruvat ljus") is a property of electromagnetic radiation which can be used to increase the information carried by light in laser physics and in classical as well as quantum-based communication systems. It has also applications in astrophysics and general relativity. Examples from different frequency ranges will be given.
