| contents | We derive the dyadic Green's function for the generalized velocity gauge in the time domain with an arbitrary parameter v and show that it reduces to the Lorenz and the Coulomb gauge Green's functions in the limit as v goes to the speed of light c and to infinity, respectively. We also derive the Green's function for the generalized Kirchhoff gauge in the frequency domain and show that it reduces to the results of the Coulomb and the temporal gauges as special cases. Together the generalized velocity and Kirchhoff gauges encompass most gauges in vector/scalar potential form in electromagnetics. |
