A third class studied is coupling, which is the mechanism by which emitted interference reaches the victim. Immunity is the opposite of susceptibility, being the ability of equipment to function correctly in the presence of RFI, with the discipline of 'hardening' equipment being known equally as susceptibility or immunity.
The second class, susceptibility, is the tendency of electrical equipment, referred to as the victim, to malfunction or break down in the presence of unwanted emissions, which are known as Radio frequency interference (RFI). EMC studies the unwanted emissions and the countermeasures which may be taken in order to reduce unwanted emissions. Emission is the generation of electromagnetic energy, whether deliberate or accidental, by some source and its release into the environment. It is also the name given to the associated branch of electrical engineering.ĮMC pursues three main classes of issue. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment. Log-periodic antenna measurement for outdoorsĮlectromagnetic compatibility ( EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage in operational equipment.
