Yes, but as frequency increases, this technique begins to fall apart,
thanks to the capacitance between the shield and the interior
conductor.

Noise pick up on long ground leads can be reduced by shielding them.
This is a well known technique in professional EMC (and electronic
security - TEMPEST) circles. The shield is connected to ground and
inner at the ground point: the 'top' end has the shield floating..
