Defining a Coaxial Cable Using Cable Dimensions
A coaxial cable consists of a core with outer insulating layers and a shield.
- On the Cables tab, in the Definitions group, click the Specified coax icon.
-
Under Cable definition, from the Definition
type
drop-down list, select Specify coaxial cable
dimensions.
-
Under Core, from the Metal
drop-down list, select one of the following:
- To create a PEC core, select Perfect electric conductor.
- To create a core consisting of a predefined metal, select a metal.
- To create a core consisting of a metal, which is not yet defined in the model, click the icon to define a metal or add a metal from the media library.
- Under Core, in the Radius field, enter the cable radius.
-
Under Core insulating layers, for each layer:
- To add a layer consisting of free space, select Free space.
- To add a coating consisting of a predefined dielectric, select a dielectric.
- To add an insulation layer consisting of a dielectric, which is not yet defined in the model, click the icon to define a dielectric or add a dielectric from the media library.
-
Under Core insulating layers, in the
Thickness field, enter the layer thickness for each
layer.
Note: If a braided shield is applied to the coaxial cable the outer radius (core + core insulation layer (s) thickness + total shield thickness) should be between the stretching limits defined for the braided shield.
-
Under Shielding, from the Shield
drop-down list, select one of the following:
- To add an outer cable shield consisting of a predefined shield, select a cable shield.
- To add an outer cable shield consisting of a shield, which is not yet defined in the model, click the icon to define a new cable shield.
-
Under Insulation layer (coating), specify the
following:
- To add a coating, select the Apply
coating check box.
- From the Medium drop-down list, specify the coating medium.
- In the Thickness field, specify the coating thickness.
- To remove the coating, clear the Apply coating check box.
- To add a coating, select the Apply
coating check box.
- In the Label field, add a unique label for the coaxial cable.
- Click Create to create the coaxial cable and to close the dialog.
