Electromagnetic interference

Definition

Electromagnetic interference (EMI) is the disruption of the normal functioning of electronic devices due to the presence of electromagnetic fields emitted by other devices or sources. This phenomenon can significantly affect sensitive plasma source technology, as variations in electromagnetic fields can lead to fluctuations in performance and stability. Understanding and mitigating EMI is essential for the reliability and efficacy of advanced plasma sources.
