We demonstrate simultaneous amplitude and phase measurements of a radio-frequency (RF) field through the use of a Rydberg atom-based sensor embedded inside a waveguiding structure. This measurement uses the Rydberg atom-based sensor in a mixer configuration, which requires the presence of a local oscillator (LO) RF field. The waveguiding structure supplies the LO field. The combined waveguide and Rydberg atom system is used to measure phase and amplitude in the near-field of a horn antenna to extract the far-field pattern.
我们展示了通过使用嵌入在波导结构内的基于里德堡原子的传感器对射频（RF）场进行幅度和相位的同时测量。该测量采用处于混频器配置的基于里德堡原子的传感器，这需要存在一个本地振荡器（LO）射频场。波导结构提供该本地振荡器场。组合的波导和里德堡原子系统用于测量喇叭天线近场中的相位和幅度，以提取远场方向图。
