Comment to: Electric field vector mapping of guided ionization waves at atmospheric pressure (arXiv :1709.03109v1)

Recently, Iseni (arXiv:1709.03109v1) reported measurements and analysis of electric field (EF) strengths adjacent to propagating ionization waves (IWs) in non-thermal atmospheric pressure He plasma jets. We demonstrate that these measurements are in error due to an improperly aligned electric field probe.
