WEBJul 1, 2022 · We investigate the Stark shift in Rydberg rubidium atoms through electromagnetically induced transparency for the measurement of direct current (dc) and 60 Hz alternating current (ac) voltages. This technique has direct application to the calibration of voltage measurement instrumentation.

WEBexperimentally investigate how the vapor-cell geometry affects the accuracy of the measurements. We find that the effects of the vapor cell on the measured rf E-field are minimized by making the vapor-cell size small compared to the wavelength of the rf E-field.

NIST Team Shows Atoms Can Receive Common Communications Signals
WEBSep 5, 2019 · Researchers use two different color lasers to prepare atoms contained in a vapor cell into high-energy ("Rydberg") states, which have novel properties such as extreme sensitivity to electromagnetic fields. The frequency of an electric field signal affects the colors of light absorbed by the atoms.
WEBa WR42 rectangular waveguide, we placed a 133Cs vapor cell in the waveguide system shown in Fig. 4. The exper-imental setup includes two directional couplers, two RF tuners, and a 34 mm section of waveguide that serves as the vapor cell. The vapor cell consists of a 34-mm length of WR42 stainless-steel waveguide with glass windows
