Abstract
We prove that an acoustic sound-hard scatterer, consisting of finitely many solid polyhedra in ℝn (n ≥ 2), is uniquely determined by the far-field patterns corresponding to n - 1 different incident waves. By suitable modifications, the method can also be used to show a similar uniqueness result in the setting without knowing the a priori physical properties of the underlying scatterer. © The Author 2009.
