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

Blog Article

Shampoo We investigate the interaction of tightly focused light with the surface-plasmon-polariton resonances of metal nanospheres.In 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 Vest find that a 100 nm silver nanosphere is very close to such an ideal oscillator.Our results have immediate implications for single nanoparticle spectroscopy and microscopy as well as plasmonics.
