Latest Patents

Jianming Zhao holds a patent for an "Apparatus and method for measuring microwave electric field at continuous frequencies based on alternating current (AC) Stark effect of Rydberg atoms." This invention involves an apparatus and method that employs a cesium vapor cell as an atomic sample. The cesium atom is excited to a Rydberg state using detection and coupling light from two laser sources. The process generates an electromagnetically induced transparency spectrum. A strong electric field is applied to induce an AC Stark frequency shift and splitting of the Rydberg energy level. The Rydberg atom acts as a frequency converter, allowing for the direct reading of the beat frequency signal of the local field and the signal field. This innovative approach enables the direct measurement of the strength of the signal field.
