View equipotential lines with the EPD100 PCB track equipotential viewer
Educational tool displays equipotential lines around PCB transmission lines
This free educational utility is a 2d boundary element method field
solver. It allows you to view the equipotential lines around a
transmission line. By seeing where the lines are densest you can
view the areas of strongest field and better understand which areas
of a structure have a greater effect on impedance.

The EPD100 can plot equipotentials on both single ended microstrips and edge-coupled surface microstrips.
Visualize track equipotential (below)
Single ended
Differential (odd mode)
The equipotential on the edge-coupled lines
may be plotted when the lines are driven in both odd mode and even
mode (more on odd and even mode.)

Si8000m and Si9000e controlled impedance design pages)
