Metal nanoparticles in strongly confined beams: transmission, reflection and absorption

Metal nanoparticles in strongly confined beams: transmission, reflection and absorption

Blog Article

We investigate the interaction of tightly focused light with the surface-plasmon-polariton resonances of metal nanospheres.In Container part particular, we compute the scattering and absorption ratios as well as transmission and reflection coefficients.Inspired by our previous work in [1], we discuss how well a metal nanoparticle approximates a point-like dipolar radiator.We find that a 100 nm silver nanosphere is very close to such an ideal oscillator.

Our results have Hat immediate implications for single nanoparticle spectroscopy and microscopy as well as plasmonics.
