Radiated electric field strength from high-power microwave systems

• Intentional electromagnetic interference (IEMI) is an emerging threat and a new electromagnetic environment that has to be considered in the mitigation of electromagnetic compatibility problems. This paper presents an attempt to estimate the upper limitations of IEMI systems based on high-power microwave devices. The upper limit of transmitted electromagnetic wave power is basically set by the microwave breakdown event. The estimate includes the properties of the electromagnetic wave propagation from the generation of the wave to the possible target.
