This is part and parcel to the world of isolated and shielded
circuits. The electrostatic shields are as effective as they are
complete in their coverage. Their contribution is measured in mutual
capacitance between the two points being isolated.

I don't have that reference and so cannot see that shield, but the only
thing the shield can do is reduce field impedance by changing the ratio
of electric to magnetic fields. In order to take either one to zero the
other must also be at zero.

Hi Tom,

There are too many contra-examples too sustain your point. What you
are talking about is radiation, this does not account for common
induction that occurs on the very short scales I've offered.
