“…Under high pressure, the diffusion losses of electrons in gas-breakdown are negligible, and breakdown occurs even at not very high ionization rate, E c is [13]- [17] In the process of discharge, the input microwave distributed in the waveguide couples in the tube. This in turn interacts with the copper wire to form SPP surface waves over the copper surface.…”

A double-spiral surface plasmon polariton (SPP) antenna is designed to produce a long-microwave plasma jet at atmospheric pressure with low power. This new structure antenna is made by an outer-tube spiral copper wire and an inner copper wire. To explore the influence of the new structure SPP exciter, many experiments are carried out in which the longest plasma jet of 13.5 cm is produced at atmospheric pressure with a power of 50 W. From the results of experiments, theoretical analysis, and field simulation by COMSOL, it is obvious that the new SPP antenna can produce longer plasma jets at a low gas flow rate, low power, and longer distance. Therefore, it is more suitable for special industrial applications for long-distance discharge.Index Terms-Microwave plasma jet (MPJ), new structural antenna, numerical simulation, surface plasmon polaritons (SPPs), theoretical analysis.

“…However, to date, no identical phenomena have been reported in the literature. [43][44][45][46][47][48][49][50][51][52][53][54][55] To gain insights into the underlying mechanisms, the authors conducted simulations to analyze the non-uniform distribution of the electrostatic field and identified that a force is exerted on the plasma jet due to the dielectric characteristics of the plasma under the external electric field. Additionally, the non-neutral characteristics of the atmospheric pressure plasma jet (APPJ), as previously reported in the authors' earlier work, result in the Coulomb force from the applied electrostatic field influencing the behavior of the plasma jet, leading to differential deflections under negative and positive voltages.…”

This study investigates the counterintuitive behaviors of a microwave‐induced atmospheric pressure plasma jet (APPJ) under the influence of an external electrostatic field applied by one or a pair of parallel electrode plates subjected to DC voltages. The findings demonstrate that the plasma jet consistently deflects toward the electrode plate with an electrostatic potential, irrespective of the direction of the applied field. The deflection becomes more pronounced with increasing voltage on the electrode plate until the ionic wind generated by the high voltage significantly affects the jet's behavior. Remarkably, a negative voltage induces a greater deflection compared to a positive voltage. To further investigate this discovery, the dielectric properties and the non‐neutral characteristics of the APPJ are analyzed, and the simulations of the electric field distribution reveal a non‐uniform distribution, which plays a crucial role in understanding the mechanism behind the observed behaviors of the plasma jet. This study provides a comprehensive understanding of the underlying mechanism driving the observed phenomena and sheds light on the collective behavior of plasma jets under non‐uniform electric fields. The findings of this study offer valuable guidelines for investigating and controlling the behavior of APPJs.
