MIL-STD-461 is a military standard that establishes the control of electromagnetic interference (EMI) emissions and susceptibility characteristics of electronic, electrical & electromechanical equipment and subsystems for military equipment. EMI encompasses any undesired signals, “noise”, generated by electronic equipment. Keeping EMI under control is crucial for military applications, because if it’s out of control, the military will be detected by the enemy and it might cause a great loss. To design a product that meets strict requirements, engineers should possess extensive knowledge of both electrical and mechanical design to avoid unintentional generation, propagation and reception of electromagnetic energy, which may cause unwanted effects, for example, physical damage in operational equipment.
