Latest Patents

Jingxu Bai 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 a cesium vapor cell as an atomic sample cell. The method excites a cesium atom to a Rydberg state using detection light and coupling light from two laser sources. The process generates an electromagnetically induced transparency spectrum. A strong electric field is applied to cause AC Stark frequency shifts and splitting of the Rydberg energy level. The Rydberg atom acts as a frequency converter, allowing for 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.
