    Discrete-dipole approximation with surface interaction: computational toolbox for MATLAB
    (Elsevier, 2011-07) Loke, Vincent L. Y.; Mengüç, Mustafa Pınar; Nieminen, T. A.; Mechanical Engineering; LOKE, Vincent L. Y.; MENGÜÇ, Mustafa Pınar
    We describe a MATLAB toolbox that utilizes the discrete-dipole approximation (DDA) method for modelling light interaction with arbitrarily-shape scatterers in free space as well with planar surface interaction (DDA-SI). The range of applicable models range from optical micromanipulation, plamonics, nano-antennae, near-field coupling and general light interaction with scatterers ranging from a few nanometers to several microns in size.

    T-matrix method for modelling optical tweezers
    (Taylor & Francis, 2011) Nieminen, T. A.; Loke, Vincent L. Y.; Stilgoe, A. B; Heckenberg, N. R.; Rubinsztein-Dunlop, H.; Mechanical Engineering; LOKE, Vincent L. Y.
    We review the use of the T-matrix description of scattering, or the T-matrix method, for the calculation of optical forces and torques, especially for the computational modelling of optical tweezers. We consider both simple particles such as homogeneous isotropic spheres, spherical shells, spheroids, and so on, and complex particles, including anisotropic particles, inhomogenous particles, and geometrically complex particles.
