Rydberg Atom-based RF Power Measurements



Matthew T. Simons, Marcus D. Kautz, Abdulaziz H. Haddab, Joshua A. Gordon, Christopher L. Holloway, Thomas P. Crowley


The power transmitted through a waveguide was determined using in-situ atom-based electric field measurements. The field distribution in the waveguide was measured using Rydberg atoms to find the maximum field, which was used to determine the power. For a proof-of-concept, the power of radio frequency fields at 17.86, 19.63, 26.53, and 33.03 GHz were measured in a WR42 waveguide. A section of waveguide was sealed and filled with cesium atoms. These atom-based measurements are self-calibrated and independent of typical power measurement methods.
