Abstract：
A variational method is presented for computations of both monopole mode and dipole mode rf quantities in metal disk-loaded waveguides. It allows for rounding of edge of a disk hole without any approximation in shape treatment. Good agreement has been found between computed and experimental results. It has higher accuracy than those of some existing simulation programs, hence provides a good tool to calculate wakefield of the tapered disc-loaded waveguides in next generation linear colliders.
