Unlocking Multi-scenario Sensing Capabilities in the Mid-ir Using Polycrystalline Silicon Metasurfaces

Simone Iadanza
2024

Abstract

The design and operational principles governing all-dielectric metasurfaces, operating in the 4 similar to 8 mu m mid-infrared band and customizable for gas and liquid sensing, are presented. A comparative analysis of silicon meta-atoms on CaF2 or Si3N4 substrates and optimization towards enhanced infrared absorption are provided.
