Kevin Weatherill is Professor of Physics in the Quantum Light and Matter group at Durham University. For over 20 years he has conducted experiments to study the interactions between atoms and light, particularly Rydberg atom systems. Recently, he has developed methods for sensing and imaging radiofrequency and terahertz fields using Rydberg atoms, and he works on a variety of funded projects with academic and industrial partners to develop these new techniques.

Radio-frequency and terahertz sensing and imaging using Rydberg atoms

Rydberg atoms are atoms for which one or more electrons are excited to a high-lying state. Rydberg atomic states are highly sensitive to external electric fields and as a result interest has grown in using ‘Rydberg receivers’ for sensing and communications in the microwave region of the electromagnetic spectrum. In this talk we present recent results where we use Rydberg atoms in thermal vapour for fast imaging in the terahertz frequency band as well as sensing radiofrequency fields in the VHF/UHF bands.
