摘要
本文提出利用物理光学PO可扩展MoM +UTD的应用范围 .理论和数值结果表明 ,PO电流的引入抛开了MoM +UTD混合中的镜像原则 ,使散射体扩展到任意复杂面 ,以及很好地解决了线天线距离弯曲曲面较近的情况下UTD技术的缺陷 .另外 ,本文指出适当比例的PO区域仍可以较准确地求解MoM区域的电流和阻抗特性 ,使得本文方法变得简单有效 ;
The extensions to the hybrid method of MoM+ UTD by Physical Optics (PO) are presented. The results of the examples show that it overcomes some disadvantages existing in the hybrid methods of MoM + UTD. It solves the problem that the reaction for the complex scattering object to wire antenna can not be dealt with the theory of the mirror principle, and the problem that wire antenna is very close to the convex surface. In the process, the result that the input impedance and the current on the MoM region can be solved only by appropriate PO region is achieved, which gives a new and practical method to analyze the EMC problem of the large electric objects quickly and effectively.
