Low pressure capacitive radio frequency (RF) plasmas are often described by equivalent
circuit models based on fluid approaches that predict the self-excitation of resonances, eg,
high frequency oscillations of the total current in asymmetric discharges, but do not provide a
kinetic interpretation of these effects. In fact, they leave important questions open: How is
current continuity ensured in the presence of energetic electron beams generated by the
expanding sheaths that lead to a local enhancement of the conduction current propagating …
