A simplified hybrid calculation method for the surface fields and near fields of surface‐current patches

Abstract

This paper presents a simplified hybrid calculation method, which enables calculation of a field very close to the surface of a perfect conducting object as well as the surface field itself. This method is based on the series electric dipole modeling (SEDM) technique, used to quickly and efficiently calculate near fields of wire antennas or objects, and the Kemptner method, used to find the surface fields of patches. The present method combines advantages of both the SEDM and Kemptner method techniques, without their weak points. Several examples in this paper show the validity of the SEDM and the simplified hybrid calculation method. © 2003 Wiley Periodicals, Inc.

Near Field and Surface Field Analysis of Thin Wire Antenna in the Presence of Conducting Cube

“…A brief introduction to the simplified hybrid method [5] for the calculation of the near and surface fields of objects efficiently is presented here. …”

“…By the appropriate treatment of singular properties, the surface current density is obtained. The Series Electric Dipole Method (SEDM) [5] is then used to model the wire current units and surface current patches. A hybrid method that combines the SEDM and the Eric Kemptner Method to improve the computational efficiency is presented.…”
