摘要:

根据在微波能量传输中可利用微波诱导等离子体进行微波整流的技术思路,制作了一款实验室用低压稳定等离子体激发装置。在2.45GHz的微波作用下,该装置可以将充气压强2666Pa的氖气激发形成等离子体,将电极置入等离子体后,可以检测到直流电压信号。研究了直流电压信号与微波激发功率、负载电阻值的关系,计算了其最大整流效率为0.05%。

Abstract:

According to the technical idea of using microwave induced plasma for microwave rectification in microwave energy transmission, a low-pressure microwave-induced plasma fixture is presented. The fixture can generate plasma in a neon bulb with the 2.45GHz microwave. A DC signal can be detected as long as the electrodes loaded in plasma. This work has investigated the rectified voltage dependence on the microwave excitation power, and the load resistance, respectively. The rectification efficiency can reach a maximum of 0.05%.

Key words: Microwave power transmission, Microwave rectification, Microwave-induced plasma, Plasma sheath
