摘　　要：提出的数值模拟过程是关于直线加速器加速结构耦合器的设计的。Mafia程序和Hfss程序分别被用来模拟一截S—Band的三腔等梯度加速结构,其两端分别为输入耦合器和输出耦合器。通过Mafia程序和Hfss程序模拟了该结构的传输特性,发现两者的模拟结果能很好吻合。We present the numerical procedures involved in the design of couplers for accelerator sections for linear colliders. The Mafia code and Hfss code is used to simulate a s-band accelerator section of constant gradiant structure, input coupler and output coupler at each end. The transmission properties of the structure are calculated with the Mafia code and hfss code , the dimensions of the couplers are adjusted until the power coupling is optimized. We find that the simulation results are almost the same.
