Interesting to note that the term Electromagnetic Effect could be triggered
by Enrico Fermi back in the 40's when he suggested that electromagnetic
effects would be observed in a nuclear explosion ( with different generation
mechanisms- Surface Burst, Air Burst, HEMP etc and different waveshapes and
levels) and lightning strikes.
Towards achieving better Electromagnetic Compatibility, this resulted in the
introduction of MIL 462 tests CS10, CS 11, CS 12, CS 13 and RS05- with most
waveforms simulated by the commonly available Solar Transient Generators in
shielded rooms and/or Bounded wave TEM cells.
In a narrow sense therefore, it could be said that to achieve good
compatibility, the equipment should withstand external natural or man made
electromagnetic effects.
Another form of environmental effect on EMC is the deterioration of EMC
gaskets, beryllium fingers and formation of oxides on an otherwise perfect
bond in salty, humid or corrosive atmosphere rendering shielding
effectiveness failure over time and/or environment, bringing up issues of
periodic EMI/EMC Preventive Maintainence in the log books!

Subject:RE: EFFECT
I agree with the substance of Ed's comment. In my experience the more usual
terminology is EME = electromagnetic environment, while E3 (E-cubed) =
electromagnetic environmental effects. Neither of these terms relates
directly to the adverse effect on rf or EMC performance due to other
environmental conditions.

Peter:
Electromagnetic Effects (EME) is a bit more comprehensive a concept
than Electromagnetic Compatibility (EMC). There are many things that
you can do with electromagnetic energy that are not necessarily
related to compatibility. RF techniques can be used to investigate or
change physical properties, protect friendly forces, confuse hostile
forces, deny use of assets, eavesdrop; well, lot's more.
I would say that EMC is a subset of EME.

Ed

Dear group,
Has anybody heard about the term EFFECT relating to EMC and
environmental
testing combined.
I am looking for any information on the topic, also any views
that
people
may have regarding the change in EMC performance due to adverse
environmental conditions
Looking forward to your comments
Peter
