AB - <p style="text-align: justify;">This work pertains to numerical aspects of a finite element method based
discontinuous functions. Our study focuses on the Interior Penalty Discontinuous
Galerkin method (IPDGM) because of its high-level of flexibility for solving the full
wave equation in heterogeneous media. We assess the performance of IPDGM through
a comparison study with a spectral element method (SEM). We show that IPDGM is
as accurate as SEM. In addition, we illustrate the efficiency of IPDGM when employed
in a seismic imaging process by considering two-dimensional problems involving the
Reverse Time Migration.</p>
