电磁格点理论和高频技术相结合的二维带劈导体的电磁散射(英文)

Combining the High-frequency Techniques with the Electromagnetic Lattice Theory for Scattering by Two-Dimensional Perfectly Conducting Bodies with Edges

一般采用混合法来分析研究带劈电大尺寸散射作各部分的电磁相互作用。在本文中，我们提出了将电磁格点理论和高频方法（PO、PTD、GTD等）相结合的混合法用以分析处理带劈电大尺寸散射体的电磁散射。数值结果表明，本文所讨论的混合技术能精确地计算目标双／单站RCS，并且能分析其散射机理。

Interaction of parts of large scatters with wedges is studied by using a hybrid method.In the hybrid method, high-frequency approximate technique (PTD, GTD, PO et al) andelectromagnetic lattice theory are used. The numerical results show that the hybrid tech-nique can be used to calculate exactly bistatic/monostatic RCS and to analysis their scatteringmechanism.
