Time-varying electric flux can indeed penetrate thin

A gapless shield made of a perfect conductor of any thickness will
completely block both electric and magnetic fields.

Hi Roy,

Given the vast gulf that separates these two observations above, and
the oblique reply in general that does not flow from your previous
question that I responded to.... It seems you are answering a topic I
have not entered into, or restating what I've already offered.

Sorry, once again I miss your point. I maintain that time-varying
electric and magnetic fields cannot exist independently, while you claim
that they can. Tom and I asked for an example of a case where they do,
and your response did not contain such an example.
