Creating a Braided Cable Shield Layer (Vance, Tyni or Demoulin)
Create a single layer, braided (Vance, Tyni, Demoulin) cable shield. For a braided shield layer, the relevant braid parameters and weave metal are specified and the Solver determines the frequency-dependent impedance (Zs + Zt) and admittance (Yt) matrix using the Vance, Tyni or Demoulin formulation.
-
On the Cables tab, in the
Definitions group, click the
Cable Shield icon.
- Under Shield layer(s), click Single to create a single-layered shield.
-
On the Inner layer tab, on the Impedance
definition tab, from the Definition
method
drop-down list, select one of the following:
- Braided (Vance)
- Braided (Tyni)
- Braided (Demoulin)
Figure 1. The Create Cable Shield dialog.
-
Under Weave, specify the following:
-
Under Filaments, specify the following:
Note: The Thickness of a Vance,
Tyni and Demoulin
shield layer is two times the filament diameter (d).
-
On the Inner layer tab, on the Admittance
definition tab, select Same as impedance
definition, from the Definition method
drop-down list to use the Vance, Tynior Demoulin formulation for the admittance matrix.
Figure 2. The Create Cable Shield dialog.
Note:The weave and filaments values are used from the impedance definition to calculate the admittance matrix.
- In the Label field, add a unique label for the cable shield.
- Click Create to create the cable shield and close the dialog.
