摘要

Light scattering is a useful tool in particle characterization. The simulation of light scattering processes can help to understand scattering characteristics and from this information about particle sizes, materials or shapes can be retrieved. In this paper we demonstrate the application of the Nullfield Method with Discrete Sources for light scattering by concave, peanut-shaped silver nanoparticles. Additionally we use the Discrete Sources Method for result validation. For the shape model a Cassini-oval based model is used, which accords to two sintered silver spheres. This model is compared to a simpler two-sphere approach by calculating the corresponding scattering patterns.
