I was wondering if the "Method of image charges" could be extended even partly or approximately to oscillating charges.(adsbygoogle = window.adsbygoogle || []).push({});

I am not considering nearly-static problems, but really radiating problems.

After all, the Poisson equation and the wave equation are rather close !

Therefore, I thought that maybe in the near-field of an (electrostatic) antenna there could be a way to re-use this good old method.

I must stress however that I want causality to be (reasonnably) ensured, as I am mainly interrested in phase and group velocities results.

Have you seem somthing similar?

Thanks
