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!

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. > -----Original Message----- > From: ed.pr...@cubic.com <mailto:ed.pr...@cubic.com> [SMTP:ed.pr...@cubic.com] <mailto:[SMTP:ed.pr...@cubic.com]> > Sent: Monday, June 28, 1999 11:43 AM > To: EMC-PSTC; PETER PHILLIPS > Subject: Re: EFFECT > > > Peter: > > Electromagnetic Effects (EME) is a bit more comprehensive a concept > than Electromagnetic Compatibility (EMC).
