摘要
该文给出了应用谱域导抗法推导的不同源激励产生的电场、磁场谱域格林函数所有分量的一般表达式．由于通过确定电流源、磁流源分别对应的等效传输线上的电压和电流，就可得到电场和磁场谱域格林函数，因此推导过程十分简便易行．应用上述谱域格林函数，分析了毫米波多层介质微带线，给出了在介质加盖和存在空气隙情况下，它们的色散特性，以及有效介电常数和特性阻抗的变化规律，
This paper presents the general and concise expressions of spectral - domain electric and magnetic Green's functions for multilayer media derived by using spectral -domain immittance approach- Because the determination of the spectral - domain Green's functions is accomplished by the investigation of voltages and currents on the equivalent circuits, which correspond to electric and magnetic current sources respec-tively, the derivation procedure is easy to follow. Finally, the above Green's functions are applied to millimeter wave multilayer microstrip lines. The dispersion characteristics and the effects of physical parameters on the effective dielectric constant and characteris-tic impedance are investigated.
