Present a design of the Emissive Microwave Power Control used for the UHF RFID Reader. 介绍一种用于适用于超高频段以上的射频读写器功率控制方案。
The emissive probe was heated by DC power supply and operated in strong emission ( I ( e0)/ I ( c0)> 1). 发射探针采用直流功率加热,并在较强电子发射条件下运行(I(e0)/I(e0)>1)。
Technology of Langmuir probe was studied to built the Langmuir probe and Emissive probe MPT plume diagnostics system including Langmuir probe and Emissive probe working power supply system Langmuir probe Emissive probe and data collection and analyzed system. 通过研究Langmuir探针测量技术,设计、开发了与发射探针MPT羽流诊断系统。其中包括Langmuir探针与发射探针工作电源、Langmuir探针与发射探针以及数据采集和数据处理软件。
A nonlinear curve fitting to the relationship between up-conversion emissive intensity and excitation light power was made, it is concluded that both red emission and green emission are the absorption process of double-photon. 通过对上转换发光强度与激发强度关系曲线的拟合,表明此材料的绿光发射和红光发射都为双光子过程。
