With the redefinition of the International System of Units (SI) that occurred in November 2018, there has been much attention on the development of atom-based sensors for metrology applications that are directly linked to the SI. In particular, great

We demonstrate a Rydberg atom-based sensor embedded in a parallel-plate waveguide (PPWG) for amplitude and phase detection of a radio-frequency (RF) electric field. This embedded atomic sensor is also capable of receiving modulated communications sig

Rydberg atoms in a vapor cell are used to measure the angle-of-arrival (AoA) of an incident radio-frequency plane wave through sub-wavelength phase measurements using a heterodyne technique.

Great progress had been made in the use of Rydberg atoms to detect the amplitude, phase, and polarization of electric fields and modulated signals. This has led to several unforeseen applications, which are discussed here.

We discuss several recent extensions of quantum radio frequency (RF) electric field sensors to antenna/receiver applications. These Rydberg atom-based sensors have been previously studied for SI-traceable RF field measurements. We demonstrate the rec

We discuss a fundamentally new method for electric (E) field strength (V/m) metrology applicable to the near-field. This new approach is significantly different from currently used field measurement techniques in that it is based on the interaction o

We are developing a fundamentally new atom-based approach for electric (E) field measurements. This new approach will lead to a self-calibrated, SI traceable, E-field measurement, providing us with the capability to perform measurements on a fine spa

Ahstract- A Rydberg atom-based electric-field measurement approach is being investigated by several groups around the world as a means to develop a new SI-traceable RF E-field standard. For this technique to be useful it is important to understand th
We recently developed a surface integral equation method where the electric field and its normal derivative are chosen as the boundary unknowns. After reviewing this formulation, we present preliminary numerical calculations that show good agreement

We are developing a fundamentally new atom-based approach for electric (E) field metrology. This technique has the capability of becoming a new international standard for E-field measurements and calibrations. Since this new approach is based on atom
