| Research Abstract |
This research project aims to develope the powerful algorithm suitable for very large matrices of the order of 10^7. The method is based on the mapping of the eigenvalue problem to lattice dynamics. The method is unique, compared with the other well known methods like the Lanezos method. Namely, the time-consuming part is mainly used for solving the time-development equation of motion. The efficiency was demonstrated by applying fractal systems and the mode analysis of sophistcated waveguides.
