This paper discusses the edge based finite element time domain method for two dimensional TE wave. The weak form solution for boundary problem of electric field vector wave equation is deduced, and the matrix equation of computation domain is obtained via the assembly of the element matrix equation derived by using edge basis function. The assembly process is considered in detail with emphasis of sign function, and the accumulatively fill-in procedure is proposed. Finally the injection of magnetic line current into source vector is also discussed and the edge based element time domain method proposed is exemplified. The example of scattering by lossy medium object is presented as well.
