RT Journal Article ID 2d075fa419ba6d6a A1 Chow, Peter A1 Kubota, Tetsuyuki A1 Namiki, Takefumi T1 A Multilevel Subgridding Approach to Multiscale Electromagnetic Simulation JF International Journal for Multiscale Computational Engineering JO JMC YR 2007 FD 2007-07-01 VO 5 IS 1 SP 19 OP 25 AB In this paper we solve the time-dependent Maxwell's equations for mobile device applications using a multilevel subgridding finite-difference time-domain method. For three-dimensional models that simulate system level details of mobile devices, the smallest features are in the nanometer (10−9m) range, leading to a time-step size in the attosecond (10−18 s) range. The feature sizes of mobile devices are in the centimeter (10−2 m) range; while for health and safety studies that include human models, features are in the meter range.
