Title:
RESONANT CAVITY, RUBIDIUM CLOCK AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/082125
Kind Code:
A1
Abstract:
Provided is a resonant cavity (400), comprising a cavity body (410), at least one rubidium bubble (420) and at least two media (431, 432). The rubidium bubble (420) and the at least two media (431, 432) are all provided in the cavity body (410), and two sides of the rubidium bubble (420) are respectively provided with at least one medium (431, 432) among the at least two media (431, 432). The distribution of a magnetic field is changed by means of media (431, 432), such that the intensity of the magnetic field is strong at a center and strong on an edge; and when the resonant cavity (400) is applied to the rubidium clock, atomic transition in the rubidium clock is improved, thereby improving the clock precision of the rubidium clock.
