H. Polaert et al., FORCES AND TORQUES EXERTED ON A MULTILAYERED SPHERICAL-PARTICLE BY A FOCUSED GAUSSIAN-BEAM, Optics communications, 155(1-3), 1998, pp. 169-179
Radiation pressure is nowadays a common tool to manipulate particles.
A large number of studies have been devoted to this technique, but mos
t of them assume that the particle under study is a homogeneous partic
le. Here we focus our attention on radiation pressure forces and torqu
es exerted by a Gaussian beam on a multilayered sphere, with a particu
lar attention devoted to the comparison between torque resonances and
absorption resonances. (C) 1998 Elsevier Science B.V. All rights reser
