“…However, the electric field strength is still higher than 50 kV/m at resonant frequency with a microwave feeding power of 15 W, which is higher than the required field strength for Ar plasma. [27] With the designed and fabricated MW-APPJ generator, experimental verification was carried out with the system demonstrated in Figure 1. Microwave generated from a solid-state microwave source (WSPS-433-200-CMFA from Wattsine Electronics Technology Co., Ltd) with frequency and power adjusting capability was introduced to the plasma generator through a circulator and a dual directional coupler.…”

A microwave atmospheric pressure plasma jet (MW-APPJ) generator based on a substrate-integrated waveguide (SIW) resonator is proposed. A thin, straight plasma needle with a length of 9 cm could be obtained. Higher than 90% of microwave feeding efficiency is obtained under a wide range of gas flow rates without a microwave matching network. As the gas flow increased from 1 to 14 L/min, a transition from

Microwave plasma jets have garnered significant attention due to their unique advantages and wide applications in numerous fields. However, the frequent collisions between electrons and neutral particles at atmospheric pressure make it challenging to generate a room-temperature plasma jet and maintain a high energy efficiency at the same time. This paper introduces a new microwave plasma jet based on a rectangular waveguide, which utilizes the surface wave propagating along the plasma jet to sustain the gas discharge. It features a simple structure, low power consumption, high energy efficiency, and strong controllability without the need for any external tuning measures. The minimum power required to ignite and stably maintain the plasma jet at atmospheric pressure is as low as 25 W and the measured lowest gas temperature at the plasma jet tail is approximately 295 K. Meanwhile, experiments show the microwave energy efficiency can be higher than 90% in a large range of input powers and gas inflow rates, while the gas temperature is maintained close to room temperature. These characteristics of our proposed surface wave plasma jet demonstrate tremendous potential in fields such as hemostasis, sterilization, wastewater treatment, semiconductor cleaning, and material processing.
