An efficient method to improve the integral equations method is presented in this article. A delta gap source generator and the fundamental mode sampling technique are employed. By employing this modified method, observation of the SWR and the creation of a large matrix in the conventional method employing a delta gap source generator are not necessary. Also, the modeling complexity and the time‐consuming computation of the conventional method, which employs the semiinfinite traveling‐wave mode, are avoided. In this article we use the coplanar waveguide short‐end discontinuity as an example to describe this method in the spectral domain. Moreover, numerical results are compared with our experimental data and they show good agreement. ©1996 John Wiley & Sons, Inc.
