    "abstract": "Conformal mapping of a slab of a two-dimensional ultrasonic crystal generate\na closed geometrical arrangement of ultrasonic scatterers with appealing\nacoustic properties. This acoustic shell is able to confine ultrasonic modes.\nSome of these internal resonances can be induced from an external wave source.\nThe mapping of a linear defect produces a wave-guide that exhibits a\nspatial-frequency selection analogous to that characteristic of a synthetic\n\"cochlea\". Both, experimental and theoretical results are reported here.",
