摘　　要：时变等离子体与微波互作用能实现微波频率的上转换,甚至可以达到太赫兹频段。本文主要采用粒子模拟方法,研究了时变等离子体介质及结构中微波频率上转换现象。所得结果对于探索新机制微波和太赫兹辐射源具有重要理论价值。The interaction between time-varying plasma and microwave can achieve microwave frequency up-conversion,and the up-conversion frequency can even reach terahertz band.Particle-in-cell(PIC)simulation is used to study the microwave frequency up-conversion in time-varying plasma mediums and time-varying plasma structures.The PIC results have important theoretical value for exploring new mechanisms of microwave and terahertz radiation sources.
