The authors develop and analyze two local discontinuous Galerkin (LDG) methods using piecewise linear polynomials for the Helmholtz equation with a first-order absorbing boundary condition in the high frequency regime. They also provide a detailed stability analysis and derive error estimates for the proposed LDG methods.
