An electromagnetic pulse (EMP) is a high amplitude, short duration, broadband pulse of electromagnetic energy, which can have devastating effects on unprotected electrical and electronic equipment and systems. The increased use of electronics in our everyday lives has augmented system vulnerability to the effects of electromagnetic fields, specifically the effects of High-altitude Electromagnetic Pulse (HEMP). Reducing the impact of potential EMP attacks on electronics begins with design. As such, protecting equipment, systems, and infrastructure is dependent upon rigorous testing and certification to ensure their ability to withstand the effects of EMP.
