Abstract:
A simple electrostaticsimulation technique based on the boundary integral method is presented. Conduction boundaries are formed by using an arrangement of line charges. The technique is well suited to analyze twoconductor open transmission lines complying or satisfying the Laplace equation. Three examples of the application of the technique are shown. The examples are originated from a slotted coaxial line structure converted to a mirror circular arcstrip line via the image theory. The numerical approach is validated by comparing the results to those obtained using variational expressions. One example considers a mirror convex circular arcstrip line with different angular slots, another treats its dual, i. e., a mirror concave circular arcstrip line and the last one deals with a twin circular arcstrip line considered as a circular version of the twin flatstrip line. A graphical procedure for generating field maps for uniform twoconductor circular geometries is also included.
