Abstract
For calculation of inductance of a linear electrode, vector potential is useful. If the electrode is in one of two media, a method of images is also useful. The paper presents a method of images for using vector potentials.
First, vector potential of a dipole composed of a linear current and two current sources in homogeneous medium is searched. Vector potentials of a semi-infinite linear current and a radiated flow plane current in homogeneous medium respectively, are also searched preliminarily. Then, images for representing the electric and magnetic fields of the dipole in one of two media are found by using the above vector potentials. Last, inductances of a horizontal and a vertical linear grounding electrodes in one of two media are computed by application of the above results.
