Discrete Dipole Approximation (DDA) is an important tool in plasmonics research. Using DDA, one can calculate scattering properties of nanoparticles at various wavelengths, polarizations and surrounding medium. The specialty of DDA is that one can calculate scattering properties of irregular shape particles (particles other than spheroids). DDA is based on …

nmie tool on Nanohub.org. This tool calculates the extinction, scattering, and absorption efficiencies of single nanoparticle (1 layer),core-shell nanoparticle (2 layer) and nanomatryushka nanoparticle (3 layer) using MIE formulation. Since 2009, I have been a regular user of Nanohub.org. www.Nanohub.orgis a website that provides …
