Experimentally Verification of Reverberation Chambers at the High Level Electromagnetic Field Strengths via Atomic Sensors

In this study, for the first time, it was investigated that the high level theoretical electrical field value generated in electromagnetic reverberation chambers was experimentally verified using a Cs atomic sensor system based on laser-atom-microwave interaction. The scope of the work, the frequency of the laser is locked to the 6S1/2 (F=4) ？ 6P3/2 (F=4) energy transition in the D2 line of Cs atomic transition. The DROR (double radio optical resonance) resonance was obtained by applying a high level uniform microwave field at the frequency of 9,192 GHz in reverberation chamber corresponding to 6S1/2 (F=3)？6P3/2 (F=4) energy transition. Zeeman sub-levels of DROR resonance were observed under the DC magnetic field and resonance on the 6S1/2 (F=3,mF=0) ？ 6S1/2 (F=4,mF=0) π-transition were investigated. The dependence of the bandwidth and amplitude of the Zeeman resonance at 6S1/2 (F=3, mF=0) ？ 6S1/2 (F=4, mF=0) π-transition and also amplitude of the DROR resonance were investigated as a function of applied uniform and isotropic high-level microwave field strength in reverberation chamber. As a result of the study, it showed that use the atomic sensors as a new sensor in experimental verification of high electromagnetic field strengths in reverberation chambers
