(a) Dependence of the general Rabi frequency \({\Omega }^{{\prime} }\) on the square root of the MW power fed to the MW planar ring antenna for the transition \(\left|0\right\rangle \) → \(\left|-1\right\rangle \) (red circles) and \(\left|0\right\rangle \) → \(\left|+1\right\rangle \) (blue squares). Considering the images of the Rabi frequency distribution with a size of 132 × 128 pixels, the values are calculated by averaging the first 8 pixels near the pixel with the maximum Rabi frequency, for an area of the size of  ~ 0.63 μm2. The error bars are calculated from the standard deviation of the previous average and added to the half width half maximum (HWHM) value of the peak in the FFT spectrum. The black line is a linear fit which shows the linear dependence of \({\Omega }^{{\prime} }\) on \(\sqrt{P}\). The right panel shows the Rabi oscillations extracted from (a), measured in the point with maximum frequency above the crossed wires of the resonator for the transition \(\left|0\right\rangle \) → \(\left|-1\right\rangle \), at the following MW powers: (b) 37.3 dBm, (c) 29.3 dBm, (d) 23.3 dBm and (e) 17.3 dBm.
