RE: When is a cable shield not a cable shield?

Dear Group, Further to my earlier email, I did a web search and found that 'groundplane' ribbon cable does exist (was vaguely aware of it from memory) and that it is claimed to have better transmission properties. Improved signal integrity usually means lower emissions. The cable comes with or

The definition or range of the term low frequency was bounded by saying the cable was electrically short. And the point is not to stop eddy currents from flowing, but to maximize and control where they flow. Both of these functions are achieved by using a high conductivity shield with low

Re: When is a cable shield not a cable shield?

I have a problem with this as well. A non-magnetic shield material protects against magnetic field radiation by providing a path for eddy currents to flow in. The eddy currents flow in such a way as to cause a magnetic field that opposes the originating field (Lenz' law). In order for the eddy

Alan, Think also in terms of magnetic fields, or area loops. The area defined by the small loop between signal lines and ground lines now have rather opaque metal plates over them. Starting around 10KHz the conductive shield kills all the magnetic fields coming out. Which were probably more
