Theoretical Analysis of the Optical Response of Silicon/Silica/Gold Multishell Nanoparticles in Biological Tissue

Figure 1

A schematic representation: a silicon/silica/gold spherical particle in space reported to the fixed coordinate system (O, x, y, and z) is illuminated by an x-polarized plane wave propagating along the z-axis. The centre of the silicon/silica nanoshell is taken as the origin of coordinates. a, b, and c are the radii of the silicon sphere, the silica shell, and the gold shell, respectively. δ measures the offset between the centre of the gold shell and the centre of the silicon/silica nanoshell.
