AI Technical Summary
Due to its high symmetry, the existing Rydberg atomic cell structure has a multi-valued and non-monotonic relationship between the AT splitting interval and the incident angle, resulting in low sensitivity and making it impossible to quickly and intuitively determine the direction of electromagnetic waves.
The Rydberg atomic electromagnetic direction finding gas cell adopts a cylindrical structure with convex sidewalls. The convex sidewalls are arc-shaped and uniform in thickness, with a non-circular cross-section. The end walls match the convex sidewalls. The inner cavity is filled with alkali metals and inert gases and encapsulated by glass thermoforming. The asymmetric convex sidewalls are designed to introduce strong direction-dependent scattering and interference, forming sharp electric field intensity peaks.
The accuracy of electromagnetic direction finding has been improved by creating a unique and sharp maximum electric field strength in the air chamber, achieving high sensitivity resolution of electromagnetic wave direction and reducing measurement error.
