The internal field enhancement spectra for four silver nanoparticle dimers with different radius ratios, at a fixed center-to-center separation a s=40 nm, b s=45 nm, c s=50 nm, and d s=60 nm. The radius of the small nanoparticle is varied while that of the large nanoparticle is kept constant at 20 nm
