Experimental observations of quasiperiodic behavior in an atmospheric-pressure dielectric barrier discharge in Helium

It has been reported earlier that quasiperiodic behavior can be observed in the numerical simulation of an atmospheric pressure dielectric barrier discharge (APDBD) under selected parameters. However, whether such phenomenon exists in reality is still unknown. This paper reports some experimental observations which could be possibly regarded as the quasiperiodic behavior in the APDBD.
