"Electrostatic shields work on principle of capacitance plate, being
grounded and side exposed to electrical/electrostatic fields."

Terman on page 1049 of his 1955 edition writes:
"Such a shield ensures that all parts of the loop will always have the
same capacitance to ground irrespective of the loop orientation in
relation to neighboring objects."

Yuri is consistent with Terman, and that is liable to be better than a
bible because it is provable and demands no faith. If wrong, it will be
rewritten with corrections.
