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.
