Rabi resonance in Cs atoms and its application to microwave magnetic field measurement

Abstract

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.

Worthwhile Relevance of Infrared Spectroscopy in Characterization of Samples and Concept of Infrared Spectroscopy-Based Synchrotron Radiation

“…e IR spectroscopy is centered on the fact that molecules absorb specific frequencies which are characteristics of their chemical structures [22]. Hence, the resonant frequencies are related not only to the bonds but also to the atoms [39]. In other words, vibrational frequency could be connected with a particular bond type [40].…”

A feasibility study of a real‐time visualization method for electromagnetic fields

“…On the other hand, in our proposed method, quantum phenomena of atoms are used in lieu of general antenna elements and receivers. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] There are already a few reports of visualization methods using atoms. However, our method is simpler and enables wider and quicker imaging compared to the previous studies.…”

Microwave Rabi resonances beyond the small-signal regime

“…The control and manipulation of microwave signals with atoms is undergoing a renaissance in the scientific world, moving beyond traditional applications such as providing the definition of the second [1][2][3][4], towards precision metrology in direct-current (DC) [5] and alternating current (AC) [6] magnetometers, and novel applications for quantum information processing, such as microwave-to-optical transduction of qubits [7][8][9]. These two examples highlight two different ways atoms are used: first, as a measurement tool to detect the fields; and second, as the interaction medium through which the fields are manipulated.…”
