Fast Computation of High-Frequency Dirichlet Eigenmodes via Spectral Flow of the Interior Neumann-to-Dirichlet Map

Barnett, Alexander; Hassell, Andrew


We present a new algorithm for numerical computation of large eigenvalues and associated eigenfunctions of the Dirichlet Laplacian in a smooth, star-shaped domain in ℝd, d≥2. Conventional boundary-based methods require a root search in eigenfrequency
