International Workshop on Optics: Simulation and Optimization

Symbolic picture for the article. The link opens the image in a large view.
From 6-10 November 2022, the Erlangen Collaborative Research Centre 1411 organises an International Workshop on “Optics: Simulation and Optimization”.

Optical properties of particulate products play a crucial role in many applications. Already the composition, size and shape of nanoparticles through tailored synthesis processes allows to vary optical properties to a large extent. On top of this, the assembly of nanoparticles into structures such as layers or supraparticles can widen the accessible property range substantially.

To be able to fully exploit this, expertise in synthesis, characterization, simulation and optimization is required.

Key topics in this workshop are thus:

  • simulation methods for optical properties
  • characterization of individual particles and particle assemblies
  • optimal design of nanoparticle products
  • model based optimization techniques in this context
  • the connection of nanoparticle design and synthesis
  • nanoparticle applications

Experts from different research areas will discuss the status quo in these fields and newly developed methodologies.
