1Device complexity
If RF tuning signal is applied without waveguide, then device complexity is reduced, but uniformity of tuning signal across sensor cell deteriorates
Solution Approach 1:
An RF waveguide is introduced as an intermediary component to transmit the RF tuning signal uniformly throughout the sensor cell. The waveguide acts as a mediator between the RF signal source and the alkali metal atoms, ensuring consistent signal distribution across the interaction region while maintaining a relatively simple overall device structure.
