| 摘 要： | RLC电路可以用来模拟原子系统中的电磁感应透明(Electromagnetically induced transparency,EIT)现象.在电容耦合RLC电路中,通过改变外部信号源的频率,测量了传输到第一个RLC回路的功率随信号频率的变化关系,观察到了由于经典干涉导致的类EIT现象.用两网孔电路模拟了A型原子系统,研究了耦合强度和失谐对类EIT信号的影响；用三网孔电路模拟了倒Y型和N型原子系统,研究了失谐对类EIT信号的影响.

| Abstract: | RLC circuits may used to simulate the phenomenon of Electromagnetically Induced Transparency(EIT) in atomic vapors.The EIT-like effect is observed in capacitor coupled RLC circuits due to the classical destructive interference,which is studied by examining the frequency dependence of the power transferred from the external generator to the resonant first loop.We investigated the effect of coupling strength and frequency detuning on EIT-like effect in two mesh circuits which used to analog three-level atom in the Λ configuration and in three mesh circuits which used to analog four-level atom in the inverted-Y and N configuration. |
