Electromagnetic Interference

Electromagnetic Interference (EMI) is the interruption of operation of an electronic device when it is in the vicinity of an electromagnetic field (EM field) in the radio frequency (RF) spectrum that is caused by another electronic device. Electromagnetic radiation involves electric (E) and magnetic (H) fields. Any change in the flux density of a magnetic field will produce an electric field change in time and space.

This change in an electric field causes another change in the magnetic field due to the displacement current. A time-varying magnetic field produces an electric field and a time-varying electric field results in a magnetic field. This forms the basis of electromagnetic waves and time-varying electromagnetics. These waves can be detected through thermography, which offers an advance alert for any unwanted situation.

Problems with EMI can be minimized by ensuring that all electronic equipment is operated with a good electrical ground system. In addition, cords and cables connecting the peripherals in an electronic or computer system should, if possible, be shielded to keep unwanted RF energy from entering or leaving. Here thermography plays an important role in detecting and providing solutions regarding Electromagnetic Interference (EMI).
