0 - Introduction to EM Phenomena, EMI and EMC image #1

All fluctuating electrical voltages and currents in conductors, whether signals, data, power or unwanted electrical noise…

  • are really electromagnetic (EM) waves guided by the physical arrangements of conductors (e.g. copper) and insulating dielectrics (e.g. PVC, fibreglass, air)…
  • giving rise to EM fields (Volts/metre: V/m, Amps/metre: A/m) in the dielectrics around the conductors…
  • their ‘field strength’ diminishing, as the distance from the conductors increases.
