    Nano-assembled plasmonic structures with gold nanoparticles (AuNPs) can control light scattering. This study shows how varying AuNP size and distribution enhances forward light direction for applications like cloaking.

    Area of Science:

    • Nanophotonics
    • Plasmonics
    • Optical Metamaterials

    Background:

    • Nano-assembled plasmonic structures offer tunable optical modulation.
    • Disorder in particle arrangements can significantly impact light scattering properties.

    Purpose of the Study:

    • To investigate the effect of gold nanoparticle (AuNP) size and filling fraction on light scattering.
    • To model and understand the role of controlled disorder in nano-assembled plasmonic structures.

    Main Methods:

    • Development of a computational model for core-shell plasmonic structures.
    • Simulations of light scattering for varying AuNP sizes (5-20 nm) and filling fractions (0.1-0.3).

    Main Results:

    • AuNP coatings redistribute scattered light power.
