DGTD for a Class of Low-Observable Targets: A Comparison With MoM and (2, 2) FDTD Alvarez Gonzalez, Jesús Alonso Rodríguez, Jose Manuel Carbajosa Cobaleda, Helena Ruiz Cabello, Miguel Díaz Angulo, Luis Manuel Gómez Martín, Rafael Antonio González García, Salvador Discontinuous Galerkin Time-domain analysis RADAR cross-section The simulation of low-observable targets requires high accuracy, both in the geometrical discretization as well as in the numerical solution of the electromagnetic problem. In this letter, we employ the well-known NASA almond, to illustrate the accuracy of the Leap-Frog Discontinuous Galerkin method, combined with a local time stepping algorithm, comparing it with the MoM and the (2,2) FDTD methods. 2018-04-11T07:21:24Z 2018-04-11T07:21:24Z 2014 journal article Alvarez Gonzalez, Jesús; et. al.
