These standing waves have regular and well-defined structure from which we can infer the angle and sign of the wavevector of the RF. We map the field using spatially resolved light sheet spectroscopy of Rydberg states of rubidium atoms in the cell. Unlike traditional phased arrays, this detection scheme is compact and low-complexity, has an active area of nearly 4\u03c0 steradians, and is sensitive to all RF polarizations. For in-plane measurements (\u03c6 = 0), we demonstrate quantitative angle-of-arrival measurements with an uncertainty on the order of one degree in an 11 s measurement. We also demonstrate that we are sensitive to the angle-of-arrival of arbitrary wavevectors in three dimensions (\u03b8 ,\u03c6 ).\n\nThis record contains all of the data presented in the figures of the above publication.", "distribution": [{"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/3801_README.txt", "mediaType": "text/plain", "title": "readme"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig1c.csv", "mediaType": "text/csv", "title": "Fig 1c"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig1d.csv", "mediaType": "text/csv", "title": "Fig 1d"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig3a.csv", "mediaType": "text/csv", "title": "Fig 3a"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig3b.csv", "mediaType": "text/csv", "title": "Fig 3b"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig3c.csv", "mediaType": "text/csv", "title": "Fig 3c"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig3d.csv", "mediaType": "text/csv", "title": "Fig 3d"}, {"downloadURL": "https://data.nist.gov/od/ds/mds2-3801/Fig4.csv", "mediaType": "text/csv", "title": "Fig 4"}], "identifier": "ark:/88434/mds2-3801", "issued": "2025-07-31", "keyword": ["Autler-Townes", "Rydberg", "electrometry", "quantum sensing", "spectroscopy"], "language": ["en"], "license": "https://www.nist.gov/open/license", "modified": "2025-04-20 00:00:00", "programCode": ["006:045"], "publisher": {"@type": "org:Organization", "name": "National Institute of Standards and Technology"}, "references": ["https://doi.org/10.1103/6dl6-754w"], "theme": ["Physics:Atomic, molecular, and quantum", "Physics:Optical physics"], "title": "Data associated with \"Angle-of-arrival detection of radio-frequency waves via Rydberg atom fluorescence imaging of standing waves in a glass vapor cell\""}
