Abstract :
A fast full-wave method for computing radiation pressure force (RPF) exerted by shaped light beams on arbitrary shaped homogenous particles is presented. The algorithm conducts low-rank decomposition on the excitation matrix consisting of all RHS´s to figure out the so-called skeleton light beams by interpolative decomposition (ID). After the solutions corresponding to the skeletons are obtained, the desired responses can be reconstructed efficiently.
