Select an arc segment, press Space button and then in the column “in conductor”, we associate them with matching conductors. Set up the properties of conductor and material. But set the middle circle to “In conduct: None”, we regard it as a non-material layer. The other settings remain the same. As shown below. Figure 2-16 Attach conductor to its property Figure 2-17 Layer 1 Gnd 2.2.5 Add materials to the model The properties of material are already given,σr of material in „schicht1‟ is 10; σr of material in „schicht2‟is 1. We use “Properties”→“Materials” to define them. Here we give both σx and σy the same number. In this way, σr will be determined as the value we need. σr =10 for schicht1. The relative electrical permittivity can‟t be 0, so we make it 1 here, but it doesn‟t influence the result. Figure 2-18 Property of material 1
σr=1 for schicht2 Figure 2-19Property of material 2 2.2.6 Place block labels and associate them with corresponding materials Set the inner block as „schicht1‟, the outer block as „schicht2‟, using function ”Operate on block labels”. Left click on a closed area to mark the label, then right click on the label and press Space button to call the menu. Then we can associate them with corresponding materials. Set the mesh size to 0.1 in this case as well. Figure 2-20 Final model
