Field distribution inside a closed guide using the finite differences method
A software package based on the finite differences method is presented. It displays the equipotential and flux lines of a closed transmission line with various dielectric layers and conductors. It is also possible to find the capacitance and characteristic impedance for simple and coupled lines. The program was developed in C and runs on a personal computer or compatible. The software has been used as a teaching aid for an undergraduate course in University of Brasilia, thus providing the students with basic concepts of electric and magnetic fields in closed guided structures.
