Abstract :
A geometric multigrid algorithm for time harmonic electromagnetic wave problems including lossy material is presented. A finite element method with edge elements and nodal elements is used to describe the problems. For the multigrid smoother, complex conjugate gradient method with Gauss-Seidel preconditioning is used
