Radiative energy from the high 
modes through the top facets (
) of the SiNC C4 (top) and three SiNCs with 
and 
similar to C4 (see also Fig. 1) and reduced heights
, and
, respectively, plotted with respect to the wavelength. The lowest graph shows an additional variation of 
to 
and 
. The graphs display modes excited by a dipole polarized along the x-direction (
) and are normalized to the highest peak in each spectrum.
