“…38,39 Such a beam is guaranteed to be an exact solution of Maxwell's equations, since each of the component plane waves in the spectrum is an exact solution, and the amplitude profile in the focal plane is guaranteed to be Gaussian. But this procedure has the disadvantages that the fields are given in integral form, and for a tightly focused beam the integration includes evanescent fields.…”

“…In this paper it is demonstrated that modeling the incident beam by an angular spectrum of plane waves 14,[37][38][39] provides what I feel to be a more intuitive and easily interpretable approach to the Gaussian-beam-cylinder scattering problem.…”

“…Our simulation uses the plane wave decomposition method of Khaled et al [29], calculating the interaction of each wave vector with the interface [30] and representing the components using standard evanescent or plane wave expansions as appropriate. This is similar to the approach used by Chang et al [31], except for our retention of non-evanescent components of the incident beams which can have a measurable effect when the angle of incidence is close to the critical angle.…”

We present a study of optically bound matter formation in a counter-propagating evanescent field, exploiting total internal reflection on a prism surface. Small ensembles of silica microspheres are assembled in a controlled manner using optical tweezers. The structures and dynamics of the resulting optically bound chains are interpreted using a simulation implementing generalized Lorentz-Mie theory. In particular, we observe enhancement of the scattering force along the propagation direction of the optically bound colloidal chains leading to a microscopic analogue of a driven pendulum which, at least superficially, resembles Newton's cradle.

“…The scattering of a plane wave from a sphere is a classical problem which was solved by Mie in 1908 [3]. More recently, various workers have considered the scattering of a Gaussian beam from a sphere [4] and its numerical implementation for other applications. To our knowledge, this is the first time this approach has been applied to a problem in optical design.…”
