Abstract

This paper presents the incorporation of material dispersion into ADI-FDTD, ADI-FDTD is an uncontionally stable mathod, allowing the time step to be increased beyond the CFL bound. ADI class problems result in a reduced execution time, while maintaining the desired accuracy level [1]. The material dispersion scheme is implemented into a one and three dimensional problem space. The scheme is shown to be unconditionally stable, and to possess an accuracy level enabling it to be applicable to ADI class problems.
