Area of Science:

• Atomic, Molecular, and Optical Physics
• Spectroscopy
• Quantum Optics

Background:

• Faraday anomalous dispersion optical filters are crucial for selective light manipulation.
• Accurate modeling is essential for optimizing filter performance, especially for atomic transitions like the Cesium D(2) line.
• Previous models may not fully incorporate hyperfine effects or arbitrary magnetic field conditions.

Purpose of the Study:
