摘要
使用离散复镜像方法 (DCIM )快速得到平面分层介质的空间域的闭式格林函数 ,避免了费时的索末菲尔德积分。给出闭式格林函数在矩量法中的应用 ,为研究微带天线的性能提供了一种数值方法。数值结果表明离散复镜像方法能够快速、准确地计算平面分层介质的闭式格林函数。
To avoid calculating the time-consuming Sommerfeld's integrals, the discrete complex image method (DCIM) is employed to obtain spatial domain closed-form Green's function for planar-layered media. By combining with the moment method, the closed-form Green's function is used to analyze microstrip antennas. Numerical results show the validity and accuracy of the method.
