论文摘要

$ \ left(\ case {v} {c} \ right)的术语的存在,该$表征了电动力延迟电位(也称为liénard-wiechert电位),被认为使人联想到多普勒效应。在这里,我们表明这些电势与多普勒移动的电磁(E.M.)场一致,该电池通过相对于实验室参考框架沿通用轨迹移动的电荷产生。当然,此处衍生的智障电位与当前文献中报道的势力正式相同。尽管如此,这项工作还是对电动力学智障场的起源开发了新的启示,同时对$ \ left一词(\ case {v} {c} {c} \ right)提供了直接的物理解释$。

The presence of the term $\left(\case{v}{c}\right)$ that characterizes the electrodynamic retarded potentials, also known as Liénard-Wiechert potentials, is thought to be reminiscent of a Doppler effect. Here, we show that these potentials are consistent with the Doppler shifted electromagnetic (e.m.) field generated by a charge moving along a generic trajectory with respect to the laboratory reference frame. Of course, the retarded potentials derived here are formally the same as those reported in the current literature. Nonetheless, this work sheds a new light on the origin of the electrodynamics retarded fields, while offering a direct physical interpretation of the term $\left(\case{v}{c}\right)$ characterizing the related potentials.
