Abstract :
This paper examines the implications of decoupling the FDTD grids between and FDTD Electromagnetic (FDTD-EM) and an FDTD Hydrodynamic semiconductor simulator. Excitation methods and responses are examined to determine feasibility for decoupling the space and time grids for significant computational savings. Additionally, a new fully-explicit leap-frog discretization of the Hydrodynamic model is is benchmarked with respect to several well known discretization methods.
