In a past job (10 years ago) another compliance engineer and myself were discussing how nice it would be to have "EMI sunglasses" while working on fixing a particularly noisy and troublesome piece of equipment. The idea was inspired by the X-ray glasses sold on the back cover of comic books.
Might be a good ad to take out in the April issue of Compliance Engineering or Conformity magazines!

The problem is that is the representation in the near field or just a plane (cross section). I will prefer a none intrusive gas or vapour that will 'glow' at different field intensity and colour, very much like a corona or aurora. :-) Now we can have a glass tank 'gas chamber' within an anechoic chamber to evaluate the field strengths in 3D. Then the argument will be that there will be different gasses for different frequent frequency ranges ;-) Just think about the possible effect on the environment. Dreams comes true when we want them to...

Translucent material which is color responsive to emi. Similar to the material on the side of batteries which responds to voltage levels. A pane of translucent material which can be put on the end of a stick much like a pane of glass or a pane of of it which could be stood from a floor support next to the product and show a pattern of emi strengths by color. Or, a thin sheet of it much like plastic wrap which can be placed on a part of a product (such as a surface or edge) which would also respond to field strength. <snip> ------------------------------------------- This message is from the IEEE EMC Society Product Safety Technical Committee emc-pstc discussion list.
