Error analysis of an energy preserving ADI splitting scheme for the Maxwell equation

Eilinghoff, Johannes; Jahnke, Tobias; Schnaubelt, Roland

We investigate an alternating direction implicit (ADI) scheme for the time-integration of the Maxwell equations with currents, charges and conductivity. This method is unconditionally stable, numerically efficient, and preserves the norm of the solution exactly in absence of the external current and the conductivity. We prove that the semidiscretization in time converges in a space similar to H$^{-1}$ with order two to the solution of the Maxwell system.
