洛伦兹规范中的多极辐射

Multipole Radiation in Lorentz Gauge

Howard J. Schnitzer

摘要:

电磁辐射的多极展开,适用于所有波长和所有距离有界源,是在洛伦兹规范,而不是通常的库仑规范。这种规范在希望保持明显的洛伦兹不变性的应用中可能是优选的。该演示文稿也作为一个有用的练习,在使用矢量球谐函数。

英文摘要:

The multipole expansion for electromagnetic radiation, valid for all wave-lengths and all distances from bounded sources, is presented in Lorentz gauge, rather than the usual Coulomb gauge. This gauge is likely to be preferred in applications where one wishes to maintain manifest Lorentz invariance. The presentation also serves as a useful exercise in the use of vector spherical harmonics.
