Bound states in the continuum (BICs) emerge in cavities with a theoretically infinite quality factor, but the experimental measurement of such modes is challenging as they are not accessible from external perturbations. The Draft approved authors realize a fully open acoustic resonator supporting BICs, that allows for the direct measurement of the in-cavity field.
