In experiments with the cold atmospheric pressure plasma jet, the frequency of the current measured near the treated target shows a mismatch with the voltage frequency. The system including the plasma device and target organizes the plasma delivery differently with changing voltage frequency and amplitude. All electromagnetic and chemical processes near the target depend on the frequency of the plasma-target contacts. In experiments and in 2D fluid model simulations, the self-organization of touching-target current is studied for voltage frequencies of 10–50 kHz and amplitudes of 2.5–6 kV. The streamer propagation through the volumetric plasma cloud outside of discharge device and the mechanism responsible for variation of touching-target current frequency are discussed.

在冷大气压等离子体射流的实验中，在处理过的目标附近测得的电流频率与电压频率不匹配。包括等离子设备和靶标的系统会随着电压频率和幅度的变化而不同地组织等离子传输。靶附近的所有电磁和化学过程都取决于等离子体-靶接触的频率。在实验和2D流体模型模拟中，研究了10–50 kHz电压频率和2.5–6 kV幅度的接触目标电流的自组织。讨论了流光在放电装置外部通过体积等离子体云的传播以及引起触摸目标电流频率变化的机制。
