Based on the similarity between the three-mesh RLC capacitive coupling circuit equation in the analog cir⁃cuit and the density matrix of the four-level atomic system,this paper studies the electromagnetically induced trans⁃parency phenomenon of the RLC circuit to the four-level atomic system and simulates the influence of the detuning of various physical quantities in the RLC circuit on the electromagnetically induced transparency phenomenon.It is found that the resonance effect of the RLC circuit is similar to the electromagnetically induced transparency phenom⁃enon in the four-level atomic system.By changing the capacitance parameters of each mesh in the RLC circuit,this experiment simulates the detuning phenomenon of the four-level atomic system to different degrees,showing that the RLC circuit can be used as a reference for the study of electromagnetically induced transparency,which opens up a new way for circuit simulation of other physical phenomena.
