RF Discharge Interference

When high-power radiating systems irradiate metal structures, RF discharges or arcs can be generated between parasitic electrodes located on the metal structures. These RF discharges have been known to cause interference to sensitive electronic systems. This paper discusses the physical and spectral properties of RF discharges in both a single and multiple source environment. Previous research is reviewed and an apparatus is shown which was used to generate RF discharges. The measured physical and spectral characteristics of discharges are given and the effect of these characteristics on some EMI aspects of RF discharges are determined.
