分层介质电、磁流场、位谱域并矢格林函数的统一形式

The Uniform Expressions of Multilayered Medium Spectral Dyadic Electric and Magnetic Current Green's Functions for Field and Potential

利用谱域导抗法推导分层介质的电磁流场位并矢格林函数各分量的统一的表达式。在谱域中通过坐标旋转，得到两组独立的等效传输线。这样问题转化为求解等效传输线的电流与电压，因而对于这类问题用一个统一的传输线公式即可得到各种情况的解，从而使推导变得非常简便。推导中考虑到了单轴各向异性介质的情况，各向同性介质可以作为它的特例。所得的公式已在多种情况下与已经发表的结果进行了校验。

The uniform expressions of multilayered medium spectral dyadic electric and magnetic current Green's functions for field and potential are derived by using spectral domain immittance approach. In spectral domain through the coordinate rotation, two independent equivalent transmission lines are obtained. Then the problem is transformed to that of finding the current or voltage of these transmission lines, which can be solved easily by only one transmission line formula. In the derivation, the horizontal and vertical sources as well as uniaxial anisotropic media are involved. The expressions may be degenerated to the case of isotropic medium. The correctness of the formulas has been examined with the published results in a large variety of cases.
