Answer to question #1: For all practical purposes, the shielding effectiveness (SE) of Cu sheet is infinite. Whatever enclosure you build, its SE will be limited not by the conductivity of Cu, but by the seams and apertures inherent in any useful structure. unless you are looking for SE at dc, Cu or Al is more than sufficient. If you need a dc magnetic field-free zone, then and only then do you have to start looking at ferromagnetic materials.
Answer to question #2: I assume you have the standards themselves (by the way, MIL-STD-461E is the present revision, which combines -461D/-462D, plus minor changes). So you are looking for additional supporting material. There are lots of people doing seminars. R&B comes to mind. I used to do a one week -461/-462 testing seminar. I have all the slides and sample test procedures. I don't know they would be worth much without the accompanying spiel and hands-on test experience, but if you have specific questions, I do have the answers. ---------- From: "Jose Miguel Rio" <[email protected]> To: <[email protected]> Subject: copper properties & MIL-STD 461 & 462 List-Post: [email protected] Date: Tue, Dec 14, 1999, 5:13 AM Dear group: I have two questions: 1) Where can I find shielding properties of copper (sheets)? 2) Where can I find information about test method of MIL-STD 461 & MIL-STD 462?
