am misunderstood. I never used the tem Faraday cage. I understand the
Faraday cage to be a completely shielded enclosure which could be a
metal automobiole body, a steel rebar reinforced concrete structure
or a screened room. These all tend to completely block both the
E-field and the H-field components of an electromagnetic wave.


Sorry, I meant "Faraday screen", which is the term you used, and I used
in my posting explaining its operation.

If you block either the E or H field, you also block the other. You
can't independently block one or the other.

Why would one pay a lot of extra money for a transformer which
eliminated capacitive coupling if it didn`t work, especially in
Havana, Cuba?


Because in order to "work" it doesn't need to "eliminate capacitive
coupling". All it needs to do is locally reduce the E/H field ratio,
which is what it does.

It might be useful to also point out the means by which these electric
and/or magnetic shields do their job. They do it not so much by
blocking as much as by diverting the fields. They serve to conduct the
field around the object that is being shielded.
