Setups employed to investigate different orientations of the propagation and polarization direction of the incident light with respect to the dielectric tensor axes within the particle. The left column shows the setups employed for the spherical particle, the right side shows the setups resulting for the spheroidal particles (indexes “p” for prolate,“o” for oblate). For all setups, the axis of rotation symmetry of the particle is directed along the Z-axis of the FDTD coordinate system; either the directions of incidence and polarization, or the orientation of the dielectric axes within the particle are altered.
