“…Recently, atom-based microwave (MW) measurement has also inspired great interest because of its potential ability to link the MW quantities with SI units. As a result, relying on various physical principles, many atom-based MW sensors have been developed [1], such as the MW power standard [16][17][18][19], MW electrometry [20][21][22][23][24][25][26][27][28][29][30][31][32], MW electric/magnetic field imaging [22,[33][34][35][36][37][38][39][40], and MW magnetometers [41,42]. As compared to traditional measurement, atom-based measurement is intrinsically calibrated where field strength is translated into Rabi frequency W via well-known atomic constants.…”

We have recently presented a technique for measuring unknown microwave (MW) fields based on Rabi resonances induced by the interaction of atoms with a phase-modulated MW field. The singlepeak feature of the measurement model makes the technique a valuable tool for simple and fast field measurement. Here we demonstrated a detailed investigation of Rabi resonance of Cs atoms inside a vapour cell. For illustration, we used the Rabi resonance-based field detection technique to determine the field strength inside an X-band cavity for applied power in the range of −21 to 20 dBm. The difference between the practical measurement and the simulation was approximately about 3% for an applied power of 20 dBm, and a higher accuracy could be expected for a larger power input.

In this paper, a quantum-based method for measuring the microwave magnetic field in free space is presented by exploring atomic Rabi resonance in the clock transition of 133Cs. A compact cesium glass cell serving as the microwave magnetic field sensing head was used to measure the spatial distribution of microwave radiation from an open-ended waveguide antenna. The measured microwave magnetic field was not restricted by other microwave devices. The longitudinal distribution of the magnetic field was measured. The experimental results measured by the sensor were in agreement with the simulation. In addition, a slightly electromagnetic perturbation caused by the glass cell was investigated through simulation calculations.

“…To validate the MW detection capability of the Rabi resonance-based system at an extended sensing frequency, we measured different frequency MW magnetic fields, with a variety of MW powers. Figure 6 plots the measured Rabi frequency Ω = 2 as a function of √ for MW magnetic fields of 5.79 GHz (red) and 10.51 GHz (purple), where is the MW incident power. As expected, the measured Rabi frequencies were linearly dependent on √ .…”

We experimentally investigated Rabi resonance-based continuously frequency-tunable microwave (MW) magnetic field detection using a single hybrid vapor cell filled with cesium and rubidium atoms. The multispecies atomic systems, with their tunable abilities in transition frequencies, enabled this atomic sensing head to cover a broader detectable MW field scope compared to the use of a single metal atom. Here, we demonstrated the simultaneous observation of atomic Rabi resonance signals with 85 Rb, 87 Rb, and 133 Cs in the same vapor cell. Using an experimentally feasible static magnetic field (DC field) below 500 Gauss, we realized a MW magnetic field strength detection with bandwidths of 4.8 GHz around 8.1GHz. The use of these three atomic systems confined in a single vapor cell also enabled the establishment of an identical MW field with the help of DC field, allowing us to perform a perfect comparison for different applications that require the same electromagnetic environment. The results may be useful for the realization and application of many atomic detectors based on different physical principles.Recently, various atom-based microwave (MW) field detection techniques have been developed, such as MW electrometry using a Rydberg atom 1-4 , MW magnetometry based on Rabi oscillations 5-8 , and MW magnetic field sensors or standards based on Rabi resonance 9-11 . Atomic-based MW detection techniques are applied widely in many fields, including inertial navigation, detection of explosions, and medical imaging of the heart and brain [12][13][14][15][16][17] . In these techniques, the strength of the MW field could be translated into a Rabi frequency via atomic constants compared to conventional MW field detection techniques. Therefore, atomic-based MW field sensors have the advantage of a high measurement accuracy and are SI-traceable 18-21 . However, these sensing techniques are generally based on single atomic specie. In the other high-accuracy measurements, multispecies atoms are becoming an ideal system for improving performance and analyzing systematic effects [22][23][24] . In this a)
