| 摘 要： | 高频电磁辐射、散射问题中激励与响应之间的线性关系成立。这一关系可用一并矢变换函数给出。因此高频电磁场问题关键在于寻求并矢变换函数。并矢格林函数理论能够给出典型电磁场问题激励与响应之间的线性关系，借助高频电磁场的局域性原理、传播与绕射遵循的费马原理，极易求得高频电磁场问题的并矢变换函数。本文讨论了高频电磁场问题中的并矢格林函数方法，研究了并矢格林函数方法在寻求并矢变换函数中的应用，得到了部分工程问题的理论结果。 |

| Abstract: | For linear electromagnetic field problems, the transformations between radiation (or scattering) field and sources (or incident waves) are linear, and are describled by linear dyadic tramform functions (DTF). The DTF for canonical problems can be derived by dyadic Creen's function method and high-frequency approximate techniques. With the DTF, together with basic behaviours of high-frequency electromagnetic field, then, a general form Of DTF can be obtained by generalizing the DTF of canonical problems. In this paper, the method for deriving DTF is investigated, and some applications are obtained. |
