摘要

我们在麦克斯韦方程的框架内分析了具有非零电面积（电场的时间积分）的电磁场脉冲存在的可能性。研究表明，在真空中没有电荷和电流的情况下，脉冲的非零电面积将导致其能量无穷大。在电荷均匀直线运动的情况下，已经形成了具有非零面积的脉冲。找到了由局域电荷系统形成这种脉冲的条件，并给出了这种系统的例子。得到了远离电荷系统的电区域的渐近性。

Pulses of the Electromagnetic Field with a Non-Zero Electric Area

We analyze the possibility of existence of electromagnetic-field pulses with a non-zero electric area (time integral of the electric field) within the framework of the Maxwell equations. It is demonstrated that in the absence of charges and currents in vacuum, the non-zero electric area of a pulse would lead to its infinite energy. A pulse with the non-zero area is shown to form already in the case of uniform and rectilinear motion of the charge. The conditions for formation of such pulses by a localized charge system are found, and an example of such a system is presented. The asymptotics of the electric area far from the system of charges is obtained.
