经典电动力学中辐射电荷的能量守恒

Energy conservation for a radiating charge in classical electrodynamics

Ashok K. Singal

摘要:

它示出,众所周知的差距在经典电动力学之间的辐射在电磁场的功率和功率损耗,计算从辐射反应的电荷进行非均匀运动,成功地解决了当一个适当的区别是在一个“实时”和那些表示在延迟时间方面的量。结果表明,带电粒子的实时辐射功率损耗的表达式与人们熟悉的拉莫尔公式或相对论情况下的Liénard公式有些不同。

英文摘要:

It is shown that the well-known disparity in classical electrodynamics between the power radiated in electromagnetic fields and the power-loss, as calculated from the radiation reaction on a charge undergoing a non-uniform motion, is successfully resolved when a proper distinction is made between quantities expressed in terms of a "real time" and those expressed in terms of a retarded time. It is shown that the expression for the real-time radiative power loss from a charged particle is somewhat different from the familiar Larmor's formula, or in a relativistic case, from Liénard's formula.
