electromagnetic emmission (EMC) (EME)
Electromagnetic emission ( EME) or electromagnetic radiation( EMR) are emissions that occur naturally and technically.
In addition to cosmic radiation, the technically generated radio emissions are those from radio waves for radio, television, radar, mobile radio, infrared radiators, microwave ovens, light, X-rays and gamma radiation.
Electromagnetic emissions can be scattered via electrical conductors in electronic circuits, components, circuit boards and devices, this is called Conducted Emission( CE), but they can also be radiated, then it is Radiated Emission( RE).
Electromagnetic emissions can cover all frequency ranges up to microwaves.
