Numerical Modelling of Optical Trapping
T. A. Nieminen, H. Rubinsztein-Dunlop, N. R. Heckenberg, A. I. Bishop
Abstract
Optical trapping is a widely used technique, with many important applications in biology and metrology. Complete modelling of trapping requires calculation of optical forces, primarily a scattering problem, and non-optical forces. The T-matrix method is used to calculate forces acting on spheroidal and cylindrical particles.
