从麦克斯韦方程组出发，建立了一种新的电磁辐射多导体传输线理论。我们用延迟电荷和电流表示标量势和矢量势，并利用连续性方程和带电阻的欧姆导体方程完成了一组MTL积分微分方程。我们自然地获得系数的潜在的P和电感L在横向电磁（TEM）模式作为奇异项的延迟标量和矢量势。我们首先分析了一个线性的单线天线系统，并表明，剩余的标量和矢量势后，删除TEM模式项负责电磁辐射。然后，我们讨论的MTL方程的两个导体传输线系统。作为一个现实的情况下，我们讨论了一个三导体传输线系统，使包括环境的影响。我们证明了一个三导体传输线系统的对称安排的第三条线是必不可少的去耦的正常模式从公共模式和天线模式。
We have constructed a new multiconductor transmission-line (MTL) theory with electromagnetic radiation starting from the Maxwell equations. We express scalar and vector potentials in terms of retardation charges and currents and complete a set of MTL integro-differential equations by using the continuity equation and the ohmic-conductor equation with resistance. We naturally obtain coefficients of potential P and inductance L in the transverse electromagnetic (TEM) mode as singular terms of the retardation scalar and vector potentials. We first analyze a linear one-line antenna system and show that the remaining scalar and vector potentials after the removal of the TEM mode terms are responsible for electromagnetic radiation. We then discuss the MTL equation for a two-conductor transmission-line system. As a realistic case, we discuss a three-conductor transmission-line system to enable the inclusion of the effect of circumstances. We demonstrate that a three-conductor transmission-line system with a symmetric arrangement around the third line is essential to decouple the normal mode from the common and antenna modes.
