Job Description

Context and Key Responsibilities

The PhD project is part of a collaborative research effort between INRIA and the CNRS-CRHEA laboratory in Sophia Antipolis, France. The project aims to develop novel numerical methods for the design and optimization of active metasurfaces, which are engineered materials that can control the behavior of electromagnetic waves.

Research Objectives

The main goal of this PhD project is to investigate and develop a reduced-order modeling (ROM) strategy for the particular modeling context of active metasurfaces. This will require extending the approach previously proposed in [LHLL21] by addressing the specificities of electrically-driven active metasurfaces and the efficient integration of the developed ANN-based ROM strategy in an inverse design workflow.

Key Activities

  • Bibliography study on existing ANN-based ROM methods
  • Formulation of an ANN-based ROM method for time-domain nanophotonics in the context of electrically-driven active metasurfaces
  • Development of the method for 3D problems in Fortran 2003 and Python
  • Detailed assessment of the novel ANN-based ROM method by considering model problems
  • Formulation and development of an inverse design workflow that leverages the novel ANN-based ROM method
  • Application of the inverse design methodology to numerical optimization of electrically-driven active metasurfaces
  • Scientific publications

Required Skills and Qualifications

The ideal candidate should have a strong background in numerical analysis for PDEs, machine learning/deep learning with artificial neural networks, and basic knowledge of physics of electromagnetic wave propagation. Proficiency in Python and Fortran 2003, parallel programming with MPI and OpenMP, and good verbal and written communication skills are also required.

Benefits and Remuneration

The PhD position offers a gross salary of 2100€ per month (years 1-2) and 2190€ per month (year 3), as well as subsidized meals, partial reimbursement of public transport costs, and other benefits.
