(a) Simulated EELS spectra taken at two electron beams for SN and HSN1 (2r = 30 nm). Each mode is labeled on the top of the figure: for SN case (black lines), mode A (2.064 eV), B (2.716 eV), C (2.967 eV), D (3.147 eV), E (3.247 eV); for HSN1 case (red lines), mode A (1.091 eV), C (2.184 eV), B (2.405 eV), D (2.746 eV), E (2.997 eV). (b,c) Simulated EELS spectra of HSNs by varying cavity size for electron beam incidence in a and b cases, respectively.
