We present the numerical procedures involved in the design of coupler cavities for accelerator sections for linear colliders. The MAFIA code is used to simulate an X-band accelerator section with a symmetrical double-input coupler at each end. The transmissions properties of the structure are calculated in the time domain and the dimensions of the coupler cavities are adjusted until the power coupling is optimized and frequency synchronism is obtained. We compare the performance of the symmetrical double-input design with that of the conventional single-input type by evaluating the field amplitude and phase asymmetries. We also evaluate the peak gradient in the coupler and discuss the implication of pulse rise time on dark current generation.
