A. Elmkies et P. Joly, FINITE-ELEMENTS AND MASS LUMPING FOR MAXW ELLS EQUATIONS - THE 3D CASE, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 325(11), 1997, pp. 1217-1222
We construct a new family of tetrahedral edge finite elements for the
resolution of Maxwell equations which solves the problem of mass lumpi
ng including the case of anisotropic media. The schemes obtained are a
nalyzed through their numerical dispersion on regular meshes.
