Metamaterial Lens Design for Space Optics using Physics-Informed Neural Networks
Dylan Everingham (COSSE student, double degree with TU Berlin)

Site of the project: TU Delft
Supervisor TU Delft: Matthias Moller and Aurele Adam (Optics group)

start of the project: October 2021

In March 2022 the Interim Thesis has appeared and a presentation has been given.

The Master project has been finished in August 2022 by the completion of the Masters Thesis and a final presentation has been given.

For working address etc. we refer to our alumnipage.

Summary of the master project:
Artificial composite materials which contain lattice nanostructure and exhibit electromagnetic response in the terahertz domain, which we call terahertz metamaterials, hold great potential for flat optics which can replace bulky lens arrays. However, traditional numerical inverse scattering models for predicting the parameters of a desired lens become ill-posed in the presence of strong multiple light scattering, such as in the case of a complex metamaterial lens lattice topology. I am investigating the use of physics-informed neural networks (PINNs) as an alternate method for solving this inverse scattering problem, with the goal of predicting an effective lens design for a specific application in space optics.
