Fig. 1. Circuit structure. Port 1 is the location of E_in, Port 2 is the location of E_dr, Port 3 is the location of E_add, and Port 4 is the location of E_th.

Fig. 2. Experimental setup.

Fig. 3. (a) Plot between the microstrip ring radius and frequency and (b) the Rabi oscillation obtained from the experiment using the system.

Fig. 4. Simulation frequency response of (a) S₂₁ and (b) S₃₁ of the Rabi antenna.

Fig. 5. Simulation of magnitude of (a) S₂₁ and (b) S₃₁ of the Rabi antenna.

Fig. 6. Simulation of the time domain of (a) normal and (b) zoom signals of the Rabi antenna. The electrons are split into two sides of time. The blue-shift on the right side has occurred with the electron time dilation, which will collapse and be returned to the origin.
