ThesisEfficient solution methodology based on a local wave tracking strategy for mid- and high-frequency Helmholtz problemsChaudhry, SharangTraditional plane wave based methods for solving wave problems in high-frequency regime, suffer from numerical instabilities when the computational domain is finely discretized and/or large enough set of basis functions is used locally to approximate . . .
ArticleAmara, MohamedWe propose a procedure for selecting basis function orientation to improve the efficiency of solution methodologies that employ local plane-wave approximations. The proposed adaptive approach consists of a local wave tracking strategy. Each plane-wave . . .
