Multilayer PCB simulated by a Field Solver

The blue lines are Electric Fields - notice how they are totally blocked by the planes. The red lines are Magnetic Fields. It is easy to see why stripline transmission lines (signal layers embedded between the planes) are far superior, from an EMI point of view, then microstrip (signal layers on the outside of the planes) that tend to emit noise.
