How to apply a travelling wave to a structure??

Hello, I am trying to design a stacked ring structure to which I want to apply a travelling voltage wave. Please help me out.

Let's assume your rings are along x and the wave is traveling along x. I'll also assume you are working in frequency domain and in a mode that allows discrete potentials to be user-specified. So you can apply discrete potentials to each ring, but with a complex factor exp(-j * k * xpos_n), where k = 2 * pi/lambda (or any other phase factor you prefer) and xpos_n is the position (say, at the middle) of the nth ring. If you want the potential wave to "travel" in the other direction, simply change the sign of k. That should do it, I think.
