RE: Shielding Effectiveness Question

Greetings Neven, There are a couple of things that need to be considered when you have an rf source close to a shield with apertures. First is the shielding properties of the shield as people have said this is very dependent upon the field impedance when you are in the near field. Second and

Re: Shielding Effectivness Question

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 Leslie Neven Pischl

Re: [SI-LIST] : Shielding Effectivness Question

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. [938] Nakano,

RE: Product Safety: A Matter of Law or Litigation?Look for a book on RF or microwave. My favorite is Fields And Waves In Communication Electronics. Look in the section on waveguides. Operate the waveguide below cutoff. A small aperture in a sheet metal with finite thickness is essentially a very

RE: Shielding Effectiveness Question

There's an article by B. Archambeault and C. Brench, entitled, Shielded Air Vent Design Guidelines from EMI Modeling in IEEE Int. Symp. On EMC, Dallas Tex., Aug. 1993, p.195. This article is referenced in a 1994 IEEE article entitled: Modeling Leakage Through Finite Apertures with TLM by

RE: UL Style Cable

Zohar Hi! I found the following links to the wire styles in UL's On-Line Component Directory at www.ul.com. As you can see the Style for the wires that you specify do not reference impedance. http://datadev80.u-l.com/stylepages/2464.doc http://datadev80.u-l.com/stylepages/2919.doc

Re: Product Safety: A Matter of Law or Litigation?

Folks -- I've seen a lot of assertions in this email chain, some of which I'd like to challenge on a factual basis. Note that I am not disagreeing with what a prudent business decision might be, but am rather challenging the assertions of what the laws state. 1. The General Product Safety
