A solid object s geometry, density, and elastic moduli completely determine its spectrum of normal modes. Solving the inverse problem - determining a material s elastic moduli given a set of resonance frequencies and sample geometry - relies on the ability to compute resonance spectra accurately and efficiently. Established methods for calculating these spectra are either fast but limited to simple geometries, or are applicable to arbitrarily shaped samples at the cost of being prohibitively slow.
