# Coaxial Cable

This option defines a coaxial cable.

Three types of coaxial cables are supported:
1. Coaxial cables defined by cable characteristics.
2. Coaxial cables defined by the cable dimensions.
3. 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).
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
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.
