Figure 3From: Microwave electrometry with bichromatic electromagnetically induced transparency in Rydberg atoms(a) Transmission spectra with \(\Omega _{m} = 0\) and (b) is the same as (a) except for \(\Omega _{m} = 0.5\Gamma \); (c) bichromatic control field-driven transmission spectra with different MW fields; (d) peak-to-peak distance Δf versus MW field strength \(\Omega _{m}\), and other parameters are the same as in Fig. 2Back to article page
