Abstract :
Aspects of the stability of time-domain update schemes for electromagnetic problems are examined based on the consideration of system amplification matrices arising from the discretization of Maxwell´s equations in the sequence space. We discuss time-domain stability for a given discretization scale and under three different assumptions of decreasing generality: general updates, general leapfrog updates, and reciprocal leapfrog updates.
