Abstract

It is well known that thermal spectral properties may be altered substantially due to roughness of a microstructure surface. This paper is aimed at attempting to develop the Finite Difference Domain Time (FDTD) algorithm to simulate the photo propagation on roughness surface and calculate its spectral properties. The Maxwell equations are transformed to the finite difference expressions with central difference conducted by so-called Yee cell, and the field split technique is employed to get scatter field FDTD expressions directly. Finally, three types of microstructure surface are involved in the numerical simulation to test the developed FDTD algorithm.
