A Novel High Energy Efficiency Dual-Channel Microwave Plasma Jet Using Strip Line

A device, which is designed based on strip line, is proposed for dual-channel plasma jets. Based on electromagnetic theory and DRUDE model, finite difference time domain algorithm and finite element algorithm are adopted to obtain the dimensions of designed device. An experimental system is established, and microwave power of 70 W can process 30 L of argon per minute, which is extremely efficient compared with traditional microwave plasma jet. Meanwhile, reflected power is measured to be 8% of incident power using a power meter, which is in good agreement with simulation results.
