Transmission line equipotential viewer
EPD100

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.  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) 

(If you need to calculate PCB Impedance, please look at the Si8000m and Si9000 Controlled impedance design pages)

Download the EPD100 free

The EPD100 requires the Microsoft .NET framework version 1.1.
The EPD100 download assumes a computer with the .NET Framework v1.1 already installed.

You can download Microsoft .NET Framework v1.1 here.
