Steffen Börm:Robust Multigrid for Maxwell's EquationWe consider a robust multigrid method for Maxwell's Equation in two dimensions. Under a number of simplifying assumptions, we prove robustness with respect to the behaviour of the coefficients in one coordinate direction and to the time-stepping parameter. The proof gives rise to a modification in the algorithm that leads to better efficiency and to an improved convergence rate estimate. Keywords: Maxwell's equations, robust multigrid, anisotropy
