Figure 1-25 New model step 2<br />
1.2.4 Add materials to the model<br />
Set up the information <strong>of</strong> material (schicht1, schicht2, center, air) <strong>and</strong> conductor (layer1,<br />
layer2, gnd), <strong>using</strong> the functions under menu “Properties”.<br />
Figure 1-26 Properties menu<br />
But set the middle circle to “In conduct: None”, we regard it as a non-material layer.<br />
Cylinder- capacitor<br />

1.2.5 Define conductor <strong>and</strong> material properties<br />
The voltage on each layer can be calculated first. If the cable is symmetric:<br />
