Abstract :
There is the resonance phenomenon in the reradiation interference on wireless station from power lines. The wire-surface simulation model, in which steel tower is represented as surface model and ground wire is represented as wire model, is excitated by vertical polarization plane wave. Based on the method of moments (MoM), the base function of wire-surface model junction point and the computation method are discussed. With various frequencies, the interference values are calculated. The possible impact factors of interference resonance, such as ground wire, conductor, number of towers and tower spans, are studied. The results show that the decisive impact factor on reradiation interference is tower spans. It is concluded that interference is mainly decided by electromagnetic scatter from power towers in short wave and above.
