Accuracy of the Skin Depth Correction for Metallic Nanoparticle Polarizability

The McLeod lab's research shows that light scattering and optical trapping calculations based on the full volume of nanoparticles is more accurate than calculations based on only the skin depth. This study suggests that a simpler model is more accurate than the skin depth model, which had been widely used by researchers for the past three decades. Read the published article.

Simulation geometry. (a) Far field scattering calculations are performed for solid and hollow gold nanospheres illuminated by plane waves. (b) Optical force calculations are performed on gold nanospheres displaced laterally by Δx from the optical axis of a Gaussian beam with λ/2 beam waist.
