Application of On-Surface MEI Method on Wire Antennas

Yaowu Liu, Kang Lan, and Kenneth K. Mei, Fellow, IEEE

Page 1301.

Abstract:

In this paper, the formulas of on-surface measured equation of invariance (OSMEI) for wire antennas are derived. The unknowns of each node on the antenna surface are expressed by the vector potential function and surface current density. The unknowns in the vicinity of each node are coupled in a linear equation and the coefficients of the linear equation are determined by the measured equation of invariance (MEI) method. The final impedance matrix obtained by the OSMEI is a highly sparse matrix. It demonstrates that the currents on thin wire antennas may also be solved by a differential equation-based formulation in addition to the conventional integral equations.
