Solution Methods for Cables
Solve a cable harness with either the Multiconductor transmission line (MTL) method or the Method of moments (MoM), only for shielded cables method.
Multiconductor Transmission Line (MTL)
- Solve the model with the multiconductor transmission line theory, hybridised with the MoM or MLFMM.
- The cable path should ideally be within λ10 of the conducting surface, although distances of up to λ5 are allowed. Alternatively, a cable reference direction can be set on the cable path.
- Connections between the cable and MoM geometry are not allowed.
Method of Moments (MoM), Only for Shielded Cables
- Solve the model with the combined MoM/MTL solver.
- Any arbitrary cable path is allowed - the height restriction of the MTL does not apply.
- Cables must be shielded.
- Connections between the cable and MoM geometry are allowed.
- Cables can be connected to one another using a shielded
enclosure that has a physical size and include radiation and grounding effects between
the cable and the antenna or circuit board.
