We are talking about the Omega mats. GK got off on a tangent about it being mumetal, which highly unlikely that it is.
See GK, that time you came back with an ad-hom in a little over 15 minutes. That’s the spirit. It’s almost believable when you do that. Great show old chap!
OregonPapa, putting my engineering hat on, as GK did for a few seconds, while I don’t see much value in the Omega mat as used, products with likely the same function, i.e. EMI absorption, or absorption with a reflection layer do have value inside equipment. They are regularly used for this. They are used to reduce the emissions from microprocessors into sensitive equipment as GK stated. They usually are not used for shielding sensitive analog as custom metal shields are used for that. They are placed around ribbon cables carrying high speed signals to be reduce EMI both inside and outside the enclosure. They are used over specific traces on PCBs to reduce EMI in the same way. They are used with RF receivers to control reflections and reduce background noise.
Mumetal like steel and other magnetic materials must be used very carefully near transformers. While it has shielding properties, it also becomes part of the magnetic circuit of those components, plus magnetic EMI components. For something like a power transformer, that could be beneficial. For an output transformer that is carefully designed, that is bad.
Uberwalz, given you don’t know how Omega mats work, and don’t seem to have any interest in finding out, what exactly are you planning to discuss? One post of I tried it and it works seems to be enough? If you knew how they work, then you would have a much better chance of applying them to their maximum effectiveness instead of just guessing.
I apologize for GK’s lack of self reflection. One would think his 18,500+ posts, many irrelevant to the conversation would give him pause that he is attracted to other posters, not the other way around. Nothing I can do about that unfortunately.
