物理光学方法应用于预测线天线辐射模型

文章主要是对线天线附近存在电大尺寸散射体模型的辐射场进行预测。物理光学方法是一种高频近似方法,主要应用于电大尺寸问题的分析。对于线天线的分析则用矩量法,即物理光学方法与矩量法相结合对模型辐射场进行预测。使用MM_PO弱耦合的思想简化计算量。通过该方法仿真实例得到了正确的结果,并且其高效性达到了预期的效果,证明了该方法的有效性。

Predicting Line_Antenna Radiation Model Using the Method of PO

The paper mainly predicts the line_antenna radiation model,using the method of PO.The method of Po is a approximate,high_frequency method,mainly for large object analysis,but for line_antenna it can't.The method of MoM can do,then the problem will be resolved by the hybrid method of MoM_PO.For further simplifying the calculational process,the paper uses a new weakly_coupling MoM_PO.Finally,examples about scattering from large electric objects are given to illustrate the hybrid methods valedity and high efficiency.
