| 摘 要： | 在推导左手分层媒质谱域并矢格林函数的基础上,分析得出了左手媒质谱域格林函数的慢收敛特性。为了将谱域格林函数转换到空域并对其进行准确的数值计算,根据左手媒质的特性,对传统的离散二级离散复镜像法提出一些改进,计算结果与变形路径的直接积分法吻合较好,验证了改进方法的正确性、精确性。运用此格林函数对一些不同参数的左手媒质微带天线辐射特性进行了全波分析,并得出它们主瓣宽度窄、低仰角等特点。

| Abstract: | Based on deducing of Spectral dyadic Green' s function of left-hand stratified media,the slow-converge characteristics of Spectral dyadic Green' s function of left-hand stratified media are analyzed and validated.In order to calculate the spatial Green' s function accurately,DCIM is improved according to the properties of left-hand material.The results are in good agreement with those achieved by direct numerical integration,which confirms the correctness,accuracy for this method.Some LH substrate microstri... |
