Analytic solutions for the longitudinal and the transverse components of the vector potential in the Lorenz gauge

Kuo-Ho Yang, Robert D. Nevels

We derive analytic solutions for the longitudinal and the transverse components of the vector potential in the Lorenz gauge for an arbitrary time-dependent charge-current distribut…

Reply to "Comments on work of Yang and Nevels 'Direct, analytic solution for the electromagnetic vector potential in any gauge' (arXiv:2507.02104)" by Onoochin (arXiv:2507.08042)

Kuo-Ho Yang, Robert D Nevels

Because of a difference between his and our results for the Coulomb-gauge vector potential, Onoochin (arXiv:2507.08042) suspected that we might have used some (so far unidentified)…

Velocity, temporal and generalized Kirchhoff gauges

Kuo-Ho Yang, Robert D. Nevels

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 gau…

Direct, analytic solution for the electromagnetic vector potential in any gauge

Kuo-Ho Yang, Robert D. Nevels

We derive an analytic solution for the electromagnetic vector potential in any gauge directly from Maxwell's equations for potentials for an arbitrary time-dependent charge-current…
