我们用共振原子探针测量微波喇叭的近场分布。在室温铯蒸气池中，利用里德伯电磁感应透明 (EIT)（一种全光学里德伯检测）研究标准微波喇叭发射的微波场。基态 6 S 1 / 2 、激发态 6 P 3 / 2 和里德堡 56 D 5 / 2 态构成三能级系统，用作原子探针，通过分析微波穿着的奥特勒-汤斯（AT）分裂来检测微波电场。我们对在近场中工作于 3.99 GHz 的微波喇叭的电场分布进行了测量，耦合了过渡 56 D 5 / 2 → 57 P 3 / 2 。微波修饰的 AT 频谱同时揭示了微波喇叭发射的场的强度和极化信息。将测量结果与使用偶极金属探针获得的现场测量结果以及电磁模拟软件 (EMSS) 的模拟进行比较。与金属探针相比，原子探针的测量结果与模拟结果更加一致。原子探针测量结果与模拟的偏差比金属探针小，提高了 1.6 dB。通过比较在场最大值两侧进行的测量来研究测量场的幅度分布的对称性。
We measure the near field distribution of a microwave horn with a resonant atomic probe. The microwave field emitted by a standard microwave horn is investigated utilizing Rydberg electromagnetically inducted transparency (EIT), an all-optical Rydberg detection, in a room temperature caesium vapor cell. The ground 6 S 1 / 2 , excited 6 P 3 / 2 , and Rydberg 56 D 5 / 2 states constitute a three-level system, used as an atomic probe to detect microwave electric fields by analyzing microwave dressed Autler–Townes (AT) splitting. We present a measurement of the electric field distribution of the microwave horn operating at 3.99 GHz in the near field, coupling the transition 56 D 5 / 2 → 57 P 3 / 2 . The microwave dressed AT spectrum reveals information on both the strength and polarization of the field emitted from the microwave horn simultaneously. The measurements are compared with field measurements obtained using a dipole metal probe, and with simulations of the electromagnetic simulated software (EMSS). The atomic probe measurement is in better agreement with the simulations than the metal probe. The deviation from the simulation of measurements taken with the atomic probe is smaller than the metal probe, improving by 1.6 dB. The symmetry of the amplitude distribution of the measured field is studied by comparing the measurements taken on either side of the field maxima.
