Missions

Designers and computer graphics scientists primarily focus on the study of visual aesthetics, while optics researchers tend to devote less attention to this aspect. Notably, nanophotonics researchers largely overlook this field, despite its universal relevance to both fine and applied arts.
The presence of nanostructures in animals and plants amplifies their remarkable visual charm and evokes profound emotional reactions. This naturally prompts us to wonder if it is possible to create entirely novel visual effects or aesthetics by investigating metasurfaces that are absent in the natural realm? For instance, with surfaces that are nanostructured at the subwavelength scale and which exist in laboratories but not yet in industries?

Activités

Addressing this question is the central objective of the ERC project UNSEEN, which has secured €2.2 million in funding for the period spanning September 2023 to September 2028. The project's core mission is to craft nanostructured surfaces, or metasurfaces, that offer fresh and unique visual appearances. The project will take place in Bordeaux in a group of physicists at the Laboratoire Photonique Numérique et Nanosciences (LP2N). This project is inherently interdisciplinary, drawing upon a diverse range of expertise, including optical metasurfaces, complex media, electromagnetic modeling, computer graphics and rendering, structural color, and nanofabrication in collaboration with other fellow groups specialized in colloidal chemistry and ebeam nanofabrication.

Compétences

The present offer concerns a PhD or postdoc position in modeling (rendering and BSDF model). You will gain a valuable experience in the domain the appearance of optical nanostructures. Your role will be:
- To render the appearance of macroscopic objects covered by the metasurfaces,
- To study how the metasurface morphology impacts the appearance and discover new appearances,
- To develop new simplified BSDF models for fast evaluation in the context of rendering,
- To develop new inverse methods to recover the morphological parameters of the metasurface from a desired appearance.
You will be a pivotal actor of the project since your expertise will directly impact the works on modeling and characterization. We aim at recruiting researchers with skills in optics and electromagnetism with a penchant for numerical studies or in numerics, possibly in computer graphics, and a penchant for optics and structural colors.

Contexte de travail

The recruited scientist will have a CNRS CDD.
