(a) Measured group shift at the central frequency 500 Hz as a function of the volume of the resonator B, showing a continuous tuning range from −55 to 29 ms, equivalent to a range of c0τg = 42λ. (b) Time-domain measurements of the incident (larger, blue pulses) and transmitted (smaller, red pulses) acoustic pressure amplitude at chosen values of VB marked by the green solid squares in (a). (c) Measured amplitude and phase advance measured across the meta-atom at various frequencies and volumes VB. The curves for a fixed frequency of 500 Hz are redrawn in the insets.
