Well I was taught that this is not quite true, but only if it is a plane (which could be the walls of an enclosure as long as they're conductive and conductively bonded across any joints etc.) - as soon as you give it length >> width (i.e. a piece of wire) it has inductance and everything goes to rat shit, and smelly piles of it.
