Fig. 4: Theoretical prediction and experimental verification: transition between the nearly full transmission (NFT) and nearly full absorption (NFA).

a For microwaves are loaded from port 1, the calculated reflectivity (r1), transmittivity (t1) and absorptivity (A1) as functions of Φ under the PZR condition. b For microwaves are loaded from port 2, the calculated reflectivity (r2), transmittivity (t2), and absorptivity (A2) as functions of Φ under the PZR condition. The square (r1(2)), diamond (t1(2)), and triangle (A1(2)) symbols in (a) and (b) are the experimental results. Color bar shows the hybridized states for different values of Φ, the abbreviations LA and LR represent level attraction and level repulsion, respectively. Open circles plotted in (a, b) indicate the PZRs do not exist at these points. c The calculated three-dimensional plot of the absorption/transmission as a function of Φ, ω1, and ω. Here, γ1/2π = γ2/2π = 1 MHz, κ1/2π = 1.7 MHz, κ2/2π = 3.3 MHz are set based on the fitting results of experimental spectra.
