Magneto-plasmonic nanostructures have been interested to the researchers in the fields such as optics, electronics and bio-engineering. They have been interested in its properties which can be explained with the concept of localized surface plasmon resonance. On the other side many researchers tried to fabricate metamaterials, the structure which shows abnormal optical property because of its permittivity and permeability which can be tuned by the periodic structures. We self-assembled nanoparticles into 1-3D suprastructure to make one kind of metamaterial. Moreover, we simulated absorption and scattering spectra of self-assembled suprastructure of Ag@Fe3O4 nanoparticles by using finite element method (FEM). We solved time-harmonic electromagnetic field distributions based on Maxwell’s equation. We integrated energy loss on the surface and the volume of nanoparticles to plot extinction, scattering and absorption. Optical properties of single Ag@Fe3O4 nanoparticle in different condition was simulated. Moreover, 1-3D and chiral self-assembled structure of single nanoparticle was also simulated.
