to overcome the time-stepping (or the pole) problem, involves coarsening the grid near the singular points, thus A method for temporal integration of the Navier-Stokes equations written in cylindrical coordinates is described. The objective is to allowing for the use of explicit time-integration. Fo

β¦ Synopsis
An eficient 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, obseruation 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 traueling-waue mode, are auoided. 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.
