Figure 1From: Local oscillator port integrated resonator for Rydberg atom-based electric field measurement enhancement(a) Energy level diagram. δ represents the energy level shift caused by the external MW field according to the AC Stark effect. (b) Geometrical details of the injection LO ports integrated resonator are presented. The material is copper with silver plating on the outer surface to increase conductivity. (c) Overview of the experimental setupBack to article page
