摘要：

The primary aim of this paper is to obtain numerical solutions for the unsteady Helmholtz equation governing harmonic acoustic problems in anisotropic trigonometrically graded materials. To achieve this, the paper proposes a method that combines Laplace transform (LT) and boundary element method (BEM). Several examples of problems related to anisotropic trigonometrically graded media are presented to illustrate that the proposed method is accurate and straightforward to implement.
