✦ Synopsis
A Galerkin edge-element solution technique for Maxwell's equations in time domain is discussed. With proper diagonal lumping of one of the mass matrices, it can be seen as a generalization to a tetrahedral mesh and its barycentric dual of the staggered-grid "nite di!erence scheme known nowadays as FDTD, or Yee's scheme. A new approach to the lumping, backed by a speci"c convergence-proof technique, is proposed.
