Article Synopsis
- Dynamic tuning of electromagnetic response in optical metamaterials allows for unique applications, with self-assembly of soft materials like liquid crystals providing tunable optical properties.
- This study demonstrates that a self-assembled system of gold nanoparticles and a photo-active chiral liquid crystal exhibits tunable epsilon-near-zero (ENZ) behavior when exposed to different light sources, showcasing significant changes in localized surface plasmon resonance.
- Experimental and theoretical analysis confirms the system's effective permittivity and ENZ behavior in the visible spectrum, enhancing its potential as a useful metamaterial in optical applications.
