Neven, To analyze the noise picked up by a wire that crosses a hole/slot in a shield, look at:

My article on "Designing Electronic Equipment for ESD-Immunity" is being edited by Printed Circuit Design magazine, and should appear on their webpage http://www.pcdmag.com/ pretty soon now. Just last week I received several E-mails from Andy Shaughnessy asking for clarification of points in my article. My list of references, which is supposed to be posted with the article, covers 70-some books and booklets, and about 1300 pertinent standards/reports/papers/articles gleaned from engineering and physics publications going back to the mid-1970's.
