Multiscale Petrov-Galerkin method for high-frequency heterogeneous Helmholtz equations

This paper presents a multiscale Petrov-Galerkin finite element method for time-harmonic acoustic scattering problems with heterogeneous coefficients in the high-frequency regime. We show that the method is pollution free also in the case of heterogeneous media provided that the stability bound of t...
