Design Of Parallel FDTD Platform With High Performance And Its Applications

With the continuous development of computer technology, the design cost of hardware and process is increasing rapidly, and full-wave electromagnetic field numerical simulation has became an important stage during various electronic products. The traditional serial numerical algorithm uses huge computer resource and time cost in order to handle very-large scale and complex structure. Under such circumstances, high effieciency parallel algorithm based on multi-core computer platform has become a mainstream choice for fast simulation. This dissertation is focused on high-effeciency parallel implementation of an integrated platform for modeling, simulation, pre-and post-processing, and visualization of various complex structure. The main work and academic contribution of this dissertation are given as follows:1. An enhanced dispersive FDTD algorithm targeting on graphene material is impelemented, and it is successfully applied on solving the transimission characteristics and tunablility of different Graphene FSS structures exicited with external electromagnetic fields.2. A new ray-tracing besed FDTD meshing algorithm using functional language is implemented with high efficiency, combined with various optimization and acceleration technologies.3. A modularized and extensible FDTD simulation platform is proposed with detailed implementation, and it is successfully applied on solving various changllenging problems in computational electromagnetics region.
