摘要
给出以互易原理为基础的光调制散射器测量法的理论推导,采用光电二极管光导开关作为散射器中间部分的光调制单元,设计出了实用的光调制散射器微波测量系统。并利用光调制散射器测量开口波导轴线的近场分布结果,与HFSS仿真结果比较具有良好的一致性。
This paper gives the deduction of optically modulated scatterer to measure radiation near-field through reciprocity principle and the structure of the optically modulated scatterer system. An applied optically modulated scatterer system is designed and photodiodes are used as modulation module. Good agreements for the results between the experiment and simulation are obtained.
