Rydberg-Atom RF Sensing
Developing and experimentally characterizing quantum-enabled RF sensors that use Rydberg atoms for electric-field measurement, direction finding, and precision RF metrology. This work combines RF and microwave engineering, atomic spectroscopy, electromagnetic modeling, signal analysis, and automated instrumentation.
- Developed subwavelength, amplitude-only approaches for RF angle-of-arrival estimation using spatial field measurements in Rydberg vapor cells.
- Characterizing sensor sensitivity and dynamic range across VHF, UHF, and microwave frequencies through calibrated RF and optical measurements.
- Investigating AC Stark shifts, RF-dressed atomic states, multiphoton coupling, and avoided crossings in Rydberg-EIT spectra using Floquet-based modeling and experimental validation.
- Studying nonlinear Rydberg-sensor response, including heterodyne detection, intermodulation products, and signal-fidelity limitations.
- Building automated RF/optical measurement systems for repeatable data acquisition, instrument control, spectral analysis, and model-to-measurement comparison.
