However, a direct link between electron energy\u2010loss spectroscopy (EELS) measurements and electromagnetic power dissipation at buried interfaces remains unclear. Here, we combine STEM\u2013EELS with full\u2010wave electromagnetic simulations to investigate SPP excitation in planar  and  stacks with 10\u00a0nm dielectric spacers. Using a finite\u2010difference time\u2010domain approach, the fast electron is modeled as a broadband electromagnetic source, enabling decomposition of extinction into absorbed and scattered power and direct comparison with EEL spectra. We show that extinction is dominated by non\u2010radiative absorption, confirming that the observed resonances originate from SPPs confined to the buried Au\u2013oxide interface. Increasing dielectric permittivity induces a redshift and modifies modal confinement, while losses remain Au\u2010dominated. Kramers\u2013Kronig analysis and simulations further confirm dielectric dispersion effects and exponential evanescent decay across the oxide layer.<\/jats:p>","DOI":"10.1002\/nap2.70285","type":"journal-article","created":{"date-parts":[[2026,9,2]],"date-time":"2026-09-02T07:36:00Z","timestamp":1788334560000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Experimental
