The objective of this thesis was the development of novel approaches to meet the demands of state-of-the-art high-performance electromagnetic (EM) finite-difference time-domain (FDTD) solvers. In a first step, a new algorithm to generate optimal grids for very complex simulations and geometries in real-time was developed and incorporated into an interactive framework. Secondly, advanced material models were investigated that are gaining in importance due to today's increased computational power. A newly developed algorithm simulates very thin metallic sheet structures and allows an efficient usage of the available high-performance computing (HPC) systems. Finally, a novel auxiliary differential equation (ADE) formulation was introduced to model linear and nonlinear dispersion. It enables the simulation of materials with arbitrary combinations of Drude, Lorentz and Debye poles, Raman scattering and the Kerr effect.

Stefan Schild received his MSc in Electrical Engineering from the Swiss Federal Institute of Technology (ETH), Zurich, Switzerland, in 2005. In spring 2005, he joined the Foundation for Research on Information Technologies in Society (IT'IS), Switzerland where he started to work on advanced FDTD techniques. In 2006, he also joined the Laboratory for Integrated Systems (IIS) at the ETH Zurich to start working towards his PhD in Electrical Engineering. His main research interests include computer simulations in general and time-domain methods in particular.
