What impedance is being calculated? Top line against dotted one below?
Calculated is the impedanz of the symmetical line, above and dotted one beneath the FR4.
It occurred to me that if I drive my top and bottom lines out of
phase, which I will, there will be an equipotential plane midway
through the board. So I could sneak a ground plane in there and
nothing would change. With the ground plane, it becomes two
microstrips, and there are lots of microstrip solvers.
Yes, that is right. The solution is approximate; no one has yet integrated an exact one.
