Near end Crosstalk Saturation-Physics Behind it

Dear Team,

For near-end crosstalk, we know that inductive and capacitive coupled current going in the same direction.

I am referring to a microstrip PCB transmission line.

I simulated using Hyperlynx.I keep on increasing the trace length.

After some time what I observed is near-end crosstalk amplitude is constant.

It is not varying with trace length.

But after some time change in trace length, does not change the near-end crosstalk amplitude. It becomes constant(Crosstalk saturation).

May I know how it is happening?
