N2 - We explore the optical multipole resonances in silicon nanoparticles of a conical shape. We use the Finite Element Method (FEM) for solving the Maxwell equations for analysis of optical properties. Harnessing the multipole decomposition technique, we study excited optical resonances in silicon nanoparticles and the influence of high-order multipoles to scattering patterns of considered nanoparticles. Non-symmetrical combination of multipole contributions due to illumination from top and bottom sides of cones is also considered. Our work provides important information about the role of high order multipoles in the light scattering by non-spherical nanoparticles in the non-symmetrical case. Our results could be applied, for example, for development of metasurfaces and metamaterials in optical range, including asymmetrical ones.
