A Modified MoM-PO Method for AnalyzingWire Antennas Near to Coated PEC Plates
Hai-Tao Chen, Guo-Qiang Zhu, Jian-Xin Luo, and Fei Yuan
A modified method of moments/physical optics (MoM-PO) hybrid method is proposed for modelling the radiation of arbitrary wire antennas near to dielectric coated metallic plates. The contribution of the surface wave is taken into account by adding modified factors into the PO operator of the traditional MoM-PO. The discrete complex image method (DCIM) is used to replace the PO operator when the observation point is close to the antenna, since the PO and the asymptotic solutions of surface wave all fail in this region. Several examples are given in this paper to prove the validity of the modified method.
