多极辐射与多极张量的规范不变约化
Multipolar radiation and the gauge invariant reduction of multipole tensors
摘要:
本文给出了用多极笛卡尔张量表示的封闭电荷和电流系统辐射的能量、动量和角动量的一般公式。除了通常的电多极子和磁多极子外,还通过作者以前的工作中给出的方法,突出了一个环形(anapole)电磁张量族,以及一些均方半径的贡献。
英文摘要:
Compact general formulae for the energy, momentum and angular momentum radiated by confined systems of charges and currents are presented in terms of their multipole Cartesian tensors. Besides the usual electric and magnetic multipoles, a family of toroid (anapole) electromagnetic tensors, as well as some mean squared radii contributions are standed out through a method given in previous works of the authors.
