SO ( 2) Duality Theory of Electric Quadrupole and Magnetic Quadrupole Radiation 电四极和磁四极辐射的SO(2)对偶理论
Finally we obtain the expressions of the radiation of electric quadrupole and magnetic quadrupole under the two formulations, and then the radiation of electric multipole and magnetic multipole are also discussed. 最后得到了电四极和磁四极辐射双矢势下表达式,并对电多极和磁多极辐射问题进行了讨论。
