FEKO is used to simulate the coupling between coaxial cable and the electromagnetic field inside a reverberation chamber.The induced current in the terminal of coaxial cable in chamber is calculated.Then,multi-column wave superposition method is provided,which is compared with model simulation.The results show that the induced current is on the state of resonance with the period of λ/2.The load of the cable terminal will not affect cable induction frequency,but will affect the peak value of the induced current.The results have certain error when using multi-column wave superposition method instead of the reverberation chamber.%为研究混响室中场对同轴线缆的耦合规律,使用仿真软件FEKO对其进行建模,对混响室中同轴线缆终端的感应电流进行仿真计算,并提出使用多列波叠加的方法与建立模型仿真得到的结果进行比较.通过不同线缆长度、仿真频率的变化,得到混响室中同轴线缆终端感应电流在其电磁波半波长整数倍频点会形成谐振；同时线缆终端负载的大小不会影响传输线感应电流的响应频点,但感应电流大小会随之改变,而在使用多列波叠加方法替代混响室模型进行仿真时,仿真结果会存在一定误差.
