Presentation Abstract:


The rigorous engineering of physical systems, such as carefully designing the load carrying members in an airplane or the optical components in a microscope, is a cornerstone in the improvement and development of new devices and the advancement of science.

Present day engineering solutions often rely on parameter studies, analytical design rules and human intuition, all of which have limitations, regularly resulting in sub-optimal devices hereby leaving room for improvement. Meanwhile, ongoing advances in mathematical modelling and growth of computational power has facilitated the development of powerful design tools, such as topology optimization, providing unprecedented freedom to explore and exploit the vast design spaces available for a multitude of physical problems.

This talk will present a range of engineering solutions created using topology optimization, with a focus on wave propagation problems within electromagnetism; give a brief introduction to structural optimization in general and a detailed discussion of density based topology optimization in particular. Recent results of using topology optimization to solve design problems considering plasmonic field localization, enhanced Raman scattering and photonic cavity design will be discussed.


Biography of the Speaker:


Rasmus holds a BSc in Physics and Nanotechnology (2011), a MSc in Computational Mathematics (2013) and a PhD-degree (2016) from the Department of Mechanical Engineering at the Technical University of Denmark (DTU). His PhD-fellowship was focused on the development, application and experimental validation of topology optimization based methods for solving wave propagation based design problems in acoustics and optics.


He currently works as a Postdoctoral researcher at DTU, where he have been involved in several projects, among which are the SunTune project and the NATEC project. The SunTune project is centered at Aarhus University and concerns the design of passive solar cell components aimed at increasing their operating efficiency. This includes the design of metallic nanoparticles for localized electromagnetic field enhancement. The NATEC project is centered at the Department of Photonics at DTU and is focused on the design of active and passive photonic structures for applications in optical data processing and terabit communication.


Currently, he is visiting the Department of Mathematics at Massachusetts Institute of Technology (MIT) as a short term scholar, where he works with Professor Steven G. Johnsons group on light matter interaction problems, treating phenomena such as Raman and Cherenkov scattering as well as designing optical metasurfaces.
