论文摘要
基于原子的微波电视标准，可通过实现稳定和均匀的测量来显示出有希望的优势。在这里，我们从理论上提出建议，然后在实验上实现一种替代的直接国际单位系统（SI） - 可接可和自校准的方法，用于测量基于电磁诱导的吸收（EIA）的微波电场强度，在冷rydberg原子中。与电磁诱导的透明度的方法相比，我们表明微波兔频率和自动镇分裂之间的等效关系更有效，并且在EIA线性区域中的实验参数更加鲁棒。此外，冷rydberg eia的缩小线宽使我们能够实现一个直接的SI-TAC-ELECTRIC-ELECTRIC-FIELD测量测量值，小至$ \ sim $ 100 $ 100 $μ\ MATHRM {\！v} \！v} \ MATHRM {cm}
The atom-based traceable standard for microwave electrometry shows promising advantages by enabling stable and uniform measurement. Here we theoretically propose and then experimentally realize an alternative direct International System of Units (SI)-traceable and self-calibrated method for measuring a microwave electric field strength based on electromagnetically induced absorption (EIA) in cold Rydberg atoms. Comparing with the method of electromagnetically induced transparency, we show that the equivalence relation between microwave Rabi frequency and Autler-Townes splitting is more valid and is even more robust against the experimental parameters in the EIA's linear region. Furthermore, a narrower linewidth of cold Rydberg EIA enables us to realize a direct SI-traceable microwave-electric-field measurement as small as $\sim$100 $μ\mathrm{\!V} \mathrm{cm}^{\!-\!1}$.
