Faraday cages and cables

AJJewsbury over 5 years ago

I've read a couple of things recently and wondered if they could go together, so a theoretical question...

would you consider the screen (foil or braid) of a cable an example of a Faraday Cage?

and so could a co-ax cable be considered simply a single core screened cable (if one with carefully controlled geometry to ensure performance at high frequencies)?

PS - so , unsurprisingly a thin wispy higher resistance braid, makes a lot poorer shield than an outer conductor made from a solid copper tube, and a well braided jacket or two is somewhere midway.

Shielding effectiveness, and transfer impedance are inversely related.
