The Physical Basis of EMC

Armed with these few basic principles, electromagnetic compatibility (EMC) issues are easilyvisualised, and problems more easily solved, using only very simple mathematics and plainEnglish.

Usually, articles like this start off by expounding Maxwell’s famous equations, sometimeseven deriving them from first principles. These are then used to solve a few simpleconstructions, such as an infinitely thin infinitely long perfectly-conducting wire suspendedover an infinite plain of perfectly conducting material. Having to this far, they then usuallyabandon the reader, as if everything that could be said, had been said.
