[HTML][HTML] Anisotropy-enhanced optical pulling force on coated nanoparticles due to Fano resonance

H Chen, Y Huang, Y Huang - Physics Letters A, 2021 - Elsevier
We investigate the effect of radial anisotropy on the optical force exerted on the anisotropic-
core/plasmonic-shell nanoparticles under the illumination of the zeroth order Bessel beam …

Optical Force and Torque on a Graphene-Coated Gold Nanosphere by a Vector Bessel Beam

B Yan, X Ling, R Li, J Zhang, C Liu - Micromachines, 2022 - mdpi.com
In the framework of the generalized Lorenz–Mie theory (GLMT), the optical force and torque
on a graphene-coated gold nanosphere by a vector Bessel beam are investigated. The core …

Graphene-tuned threshold gain to achieve optical pulling force on microparticle

HL Chen, Y Huang - Chinese Physics B, 2021 - iopscience.iop.org
We investigate optical force on a graphene-coated gain microparticle by adopting the
Maxwell's stress tensor method. It is found that there exists a threshold gain in obtaining the …
