摘要
本文提出一种快速分析理想导体电磁散射及辐射问题的新近似模型 .应用这种方法 ,一个理想导体通常被分成两个区域 ,在靠近源或者入射波照射区域 ,利用矩量法求解 ,而另一个区域的电流则通过近似方法获得 .与现有的混合方法相比 ,新模型给出了更好的结果和物理解释 .无论是二维还是三维情况 ,数值模拟结果都验证了该方法的准确性 .
A new approximate model is proposed for the efficient implementation of the electromagnetic scattering and radiation by perfectly electrical conducting (PEC) objects using the method of moments (MOM).In the new model,the PEC object under consideration is divided by two parts,where MOM is performed only on the first part after making a closed-form approximation for the electric current on the second part.Compared with the published hybrid methods,the new model gives better physical explanations.The new model is valid for both two-dimensional and three-dimensional cases.Numerical examples are given for validation of the model.
