Researchers have developed a novel approach using Wavelet-Encoded Fourier Neural Operators (FNOs) to solve complex eigenvalue problems in physics, specifically for metamaterial design. This method effectively predicts multiple eigenmodes of the elastic wave equation, which represent deformation modes of acoustic waves in arbitrary metamaterial geometries. The wavelet encoding is crucial for matching the FNO's spatial-spectral structure, enabling accurate mode selection and prediction even with geometric discontinuities. This surrogate model significantly accelerates the simulation phase of metamaterial design, achieving a three-orders-of-magnitude speedup compared to traditional finite element analysis while maintaining high fidelity.
