## Abstract Helmholtz equations with variable coefficients are known to be hard to solve both analytically and numerically. In this paper, we introduce a numerical multigrid solver for oneโ€dimensional Helmholtz eigenvalue problems with periodic potentials and solutions. The solvers employ waveโ€“ray
