In particular, there will be waves propagating along the plates with sufficiently short wavelengths, and (setting aside the issue of what the potential even is and how the E-field is related to it) you won't be able to assume a constant potential on each plate at a given time. | |

Unfortunately I don't have any with me right now. Still, a little Googling will take you a long way: see for instance here, here and here. | |
