Abstract:
A simple electrostatic-simulation 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 two-conductor 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 arc-strip 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 arc-strip line with different angular slots, another treats its dual, i. e., a mirror concave circular arc-strip line and the last one deals with a twin circular arc-strip line considered as a circular version of the twin flat-strip line. A graphical procedure for generating field maps for uniform two-conductor circular geometries is also included.
