Abstract: | This thesis deals with the development and analysis of a discretization method and the error controlled adaptation of spatial and temporal discretizations in context of the time-dependent Maxwell equations. To this end, a hp space-time Galerkin discretization for Maxwell’s equations, allowing for local adaptation of the polynomial approximation order p as well as the local meshsize h, is developed and analyzed. Furthermore, the developed discretization is extended to problems with waveguide structure, in order to efficiently model waveguide ports. For the purpose of local adaptation and control of the global discretization error, a posteriori error estimates for quantities of interest such as scattering parameters or farfield quantities are derived and employed within an hp-adaptive algorithm. While such adjoint based a posteriori error estimates are available for many other problems, its application to the present problem has been newly developed in this thesis. |
