T-matrix calculation via discrete-dipole approximation, point matching and exploiting symmetry
Vincent L. Y. Loke, Timo A. Nieminen, N. R. Heckenberg +1
We present a method of incorporating the discrete dipole approximation (DDA) method with the point matching method to formulate the T-matrix for modeling arbitrarily shaped micro-s…
Symmetry and the generation and measurement of optical torque
Timo A. Nieminen, Theodor Asavei, Vincent L. Y. Loke +2
A key element in the generation of optical torque in optical traps, which occurs when electromagnetic angular momentum is transferred from the trapping beam to the trapped particle…
Modelling optical micro-machines
Vincent L. Y. Loke, Timo A. Nieminen, Agata M. Branczyk +2
A strongly focused laser beam can be used to trap, manipulate and exert torque on a microparticle. The torque is the result of transfer of angular momentum by scattering of the las…
Towards efficient modelling of optical micromanipulation of complex structures
T. A. Nieminen, V. L. Y. Loke, A. M. Branczyk +2
Computational methods for electromagnetic and light scattering can be used for the calculation of optical forces and torques. Since typical particles that are optically trapped or…
