A Hybrid Algorithm for Field-to-line Coupling Analysis above Ground

A hybrid algorithm combined parabolic equation (PE) and integral e quation (IE) is presented for analyzing electromagnetic field coupling to conducting thin-wires above ground. In this algorithm, PE with alternating direction implicit (ADI) difference technology, is applied to calculate the field above ground, which is use d as the excitation of the thin-wires. Combined with spatial interpolation technique, the induced currents on wires are simulated by IE solved via the moment method (MoM). Examples are given to illustrate the correctness of the presented algorithm by comparing the results with those of full-wave method (FWM).
