Glad you liked it!

Really very good, thank you. But the assertion that traces are transmission lines through the dielectric is only a very crude approximation, although much better than none. If the conductor is not a mirror-perfect enclosed rectangular wage-guide, then the current propagates via EM radiation OUTSIDE of the trace! This is basic QED.
