Coaxial Cable
This option defines a coaxial cable.
Figure 1. The CD - Cable cross section definition dialog.
Three types of coaxial cables are supported:
- Coaxial cables defined by cable characteristics.
- Coaxial cables defined by the cable dimensions.
- Internally defined database of cables.
Parameters: Coaxial cables defined by cable characteristics
- Cross section label
- The label of the cross section.
- Shield label
- The label of the shield (as defined in the SH card).
- Outer radius
- The outer radius of the shield.
- Magnitude of the characteristic impedance (Ohm)
- The magnitude of the characteristic impedance of the cable.
- Attenuation (dB/m)
- Specify the attenuation of the coaxial cable in dB/m.
- Velocity of propagation (%)
- Specify the propagation speed through the coaxial cable relative to the speed of light.
Parameters: Coaxial cables defined by cable dimensions
- Shield
-
- Shield label
- The label of the shield (as defined in the SH card) to be used
- Shield outer radius
- The outer radius of the shield.
- Core
-
- PEC
- Select this option to set the core of the cable to PEC.
- Material label
- The label of the metallic medium (as defined in the DI card) to be used for the core.
- Core radius
- The radius of the core.
- Number of insulation layers
- The number of the insulation layers in the cable.
- Material label
- The label of the material (as defined in the DI card) to be used for the insulation layers.
- Thickness
- The thickness of the insulation layers.
- Cable per-unit-length parameters accuracy
- The Cable per-unit-length parameters accuracy can be increased from Normal (default) to High or Very high.
Parameters: Internally defined database of cables
No parameters are specified, but a predefined coaxial cable type can be selected from the drop-down list. Several common types of shielded cables are included in this list.
