(a), The simulation scheme (inset shows coordinate directions). The normal incident light was along the z-direction and polarised along the y/x-direction. (b), Far field angular scattering, which shows the behaviour of the scattered field in the far zone in the x-y and y-z planes. The vertical direction numbers represent the relative intensity. (c and d), The electric field intensity scattered by the VO2-based particle film is indicated by a colour scale in the x-y and y-z planes.
