摘要

本文提出了一种分析复杂电磁场边值问题的新的数值方法——场域分合解。利用该方法,可以将各种同轴辐射体视为bvp,并对其精确的全局解进行精确求解。给出了三个示例来说明:开放式同轴线辐射器、半球形单极子辐射器和被介电壳覆盖的半球形单极子天线。将全局数值边界条件与有限元法相结合,给出了场域划分组合解。

Accurate global solutions of EMF boundary-value problems of coaxial radiators
The authors present a new numerical method called the field domain partition-combining solution for the analysis of complicated electromagnetic field (EMF) boundary-value problems (BVPs). Using this method, a variety of coaxial radiators can be treated as BVPs and precisely solved for their accurate global solution. Three examples are given for illustration: an open-ended coaxial line radiator, hemispherical monopole radiators, and a hemispherical monopole antenna covered by a dielectric shell. The field domain partition-combining solution is based on a combination of the global numerical boundary condition and the finite element method.<>
