在时空的克利福德代数框架内，本文构建了一种协变电动力学，其中四维势的导数除了包含电磁二重矢外，还包含一个标量场S。推导了广义麦克斯韦方程组，当S=0时该方程组可退化为经典麦克斯韦方程组。得到了能量-动量张量、相应的守恒律以及广义洛伦兹力密度。研究表明，在自由空间中，场S存在波动解，称为标量S波；确定了自由S波的结构与能量特性，以及其可能的产生源和实验探测条件。
英文摘要
Within the Clifford algebra of spacetime, a covariant electrodynamics is formulated in which the derivative of the four-potential contains a scalar field (S) in addition to the electromagnetic bivector. A generalized system of Maxwell equations is derived that reduces to the classical Maxwell system when S=0. The energy-momentum tensor, the corresponding conservation laws, and a generalized Lorentz force density are obtained. It is shown that, in free space, the field S admits wave solutions, termed scalar S-waves. The structure and energy characteristics of a free S-wave, as well as its possible sources and the conditions for its experimental detection, are determined.
