碩士 === 國立成功大學 === 機械工程學系碩博士班 === 99 === The advancements in micro/nano fabrication make it feasible to obtain complex and diverse structures, which have great potentials in energy conversion and optical elements. Therefore, this work focuses on the numerical ability development for optical and radiative properties of micro/nano periodic structures and random rough surfaces. It is hoped that the success of the work not only saves the cost of fabrication but also measurement or develop potential applications. Here, I developed the Fortran programs based on the finite difference time domain (FDTD) method. The main contributions of this thesis are listed below. First, obtained radiative properties of 1D and 2D periodic structures as well as those of random rough surfaces agree well with those from published literatures. Second, programs were also established for 1D and 2D random rough surface generation such that the standard deviation and correlation length of rough surface height can be controlled. Third, makes it feasible to acquire radiative properties of periodic structures for the zenith angle up to 60 degrees combining FDTD method with multiple unit cell method.
