Modellansatz - English episodes only

Nanophotonics is one great path into our future since it renders possible to build e.g. absorber, emitter or amplifier on a scale of a few dozen nanometers. To use this effectively we will have to understand firstly the resonances of plasmons and secondly the interaction of electromagnetic waves with complex media. Here on the one hand we can model light as waves and describe what is happening for the different frequencies of monochromatic light waves. We have to model the evolution in air or in

To separate one single instrument from the acoustic sound of a whole orchestra- just by knowing its exact position- gives a good idea of the concept of wave splitting, the research topic of Marie Kray. Interestingly, an approach for solving this problem was found by the investigation of side-effects of absorbing boundary conditions (ABC) for time-dependent wave problems- the perfectly matched layers are an important example for ABCs. Marie Kray works in the Numerical Analysis group of Prof. Grote

Prof. Francisco Sayas from the Department of Mathematical Sciences of the University of Delaware in Newark has been visiting our faculty in June 2015. He is an expert in the simulation of scattering of transient acoustic waves. Scattering is a phenomenon in the propagation of waves. An interesting example from our everyday experience is when sound waves hit obstacles the wave field gets distorted. So, in a way, we can "hear" the obstacle. Sound waves are scalar, namely, changes in pressure. Other

Prof. Enrique Zuazua is a Distinguished Professor of Ikerbasque (Basque Foundation for Science) and Founding Scientific Director at the Basque Center for Applied Mathematics (BCAM), which he pushed into life in 2008. He is also Professor in leave of Applied Mathematics at the Universidad Autónoma de Madrid (UAM) and a Humboldt Awardee at the University of Erlangen-Nuremberg (FAU) as well. He was invited by the PDE-group of our Faculty in Karlsruhe to join our work on Wave Phenomena for some days
