Microwave electric field broadband sensing device based on rydberg atom, preparation method and system
By integrating an ITO transparent conductive film into a Rydberg atomic gas cell, the problems of glass wall shielding and metal electrode disturbance were solved, enabling high-precision measurement of DC, low-frequency, and broadband microwave electric fields. This expanded the frequency coverage and improved the self-calibration capability and consistency of the measurement.

AI Technical Summary
Existing Rydberg atomic gas cells suffer from problems such as glass wall shielding effect, built-in metal electrode disturbance, and narrow frequency coverage when measuring microwave electric fields, making it difficult to achieve high-precision measurement of DC, low-frequency, and broadband tunable microwave electric fields.
A parallel plate electrode pair is formed by depositing an indium tin oxide (ITO) transparent conductive film on the inner surface of a glass substrate. Combined with high-temperature thermal bonding sealing technology, a closed atomic gas cell is constructed to achieve effective loading of DC/low-frequency electric fields and low-disturbance measurement of microwave electric fields.
It overcomes the glass wall shielding effect, reduces microwave electric field disturbance, expands the frequency range and dynamic range, supports multi-mode measurement, has self-calibration capability and high repeatability, and is suitable for electric field sensing and electromagnetic compatibility testing in power systems.
