I would appreciate
Neven,
There are quite a number of books addressing the shielding effectiveness
analysis. Personally, I will recommend two of them:
1. White: EMC Handbook, Volume 3: Shielding
2. Ott: Noise Reduction Techniques in Electronic Systems, Chapter 6: Shielding
Hope this helps

Neven,
To analyze the noise picked up by a wire that crosses a hole/slot in a shield,
look at:
[831] Lin, Guoxian, Electromagnetic Excitation of a Wire Crossing a Long Slot
in an Infinite Plane, Electromagnetic Compatibility 1989, Zurich,
Switzerland, Mar. 7-9, 1989, pp. 89-92.

In the near field one must know whether the offending emmiter is mostly
generated
from a magnetic loop or electric field antenna structure. Once that is known,
the
eventual transmitted portion can be computed. If your shielding is non Fe, Ni
or Co
and the source is of a magnetic loop
RE: Product Safety: A Matter of Law or Litigation?Neven,
I did some rather intensive analysis of shielding effectiveness
over the course of several weeks a while back. Results were
extremely informative.
I've read a couple of fields and waves books for slot analysis.
Rau is the one I
Neven,
The phenomenon you describe is pretty well understood and covered in the
literature. What follows is from memory but is essentially the idea, so
check the literature! Basically what you have, with a small opening, is a
waveguide operating below its cutoff frequency. While it is true

RE: Product Safety: A Matter of Law or Litigation?I would appreciate if anyone
could let me know if there are any references (books, application notes,
anythig ..) that deal with shielding efectivness in cases when a source is
close to an (electrically small) opening in a shield (enclosure). In
