Study on Rydberg Atomic-based Millimeter Wave Electric Field Measurement

The inherent advantages of the Rydberg atom, including its sensitivity, dynamic range and immunity to electromagnetic interference, allow for precise electric fields and can be applied in a variety of applications such as telecommunications, electronics and environmental monitoring. In this paper, we propose a method for accurately measuring the electric field in a wide frequency range from several GHz to THz frequency by utilizing the Rydberg state of non-metallic Rb atoms, and compare existing antenna measurements and a comparison provides insight into the performance and shows that it is a promising technology for electric field sensing using the unique properties of Rydberg atoms.
