Mahmoud Elsawy

Welcome to my personal website! I am a permanent researcher as Inria Starting Faculty position at Atlantis project-team located at Centre Inria d'Université Côte d'Azur, France. I hold a Ph.D in Physics from the University of Aix-Marseille, France, where I specialized in Optics, Photonics and Image processing. As a researcher in the field of electromagnetic modelling, I have dedicated my career to designing and modeling complex linear and nonlinear nanophotonic components that can be fabricated and characterized experimentally. My research focuses on unlocking the full potential of these components for a range of practical applications. I am particularly captivated by the vast potential of Metasurfaces - both active and passive - for various applications in fields such as optical communications, imaging, and sensing. With my passion for exploring new technologies, I am excited to continue investigating the potential of Metasurfaces to transform these fields to the realistic practical industrial level . I invite you to explore my website to learn more about my research and expertise.

Universal active metasurface modelling approach with ultimate performance .

Optimization of metasurfaces under geometrical uncertainty using statistical learning.

Multiobjective optimization for the design of 3D RGB Metalens.

Review article on various numerical optmization methods for metasurface designs.

News & Upcoming events

I will give a talk during the SLEIGHT Science Event #13 de l'EUR Manutech-SLEIGHT (9-14 Janvier 2025)

I will attend the PIERS 2025, scheduled to be held in Abu Dhabi May 4-8, 2025
