摘要：
A 3D structure-preserving finite difference scheme developed in time domain and non-staggered grids will be presented. Besides preserving symplecticity and dispersion equation, we are also aimed to locally conserve divergence-free electrical and magnetic fields. For accelerating large-sized simulation on electromagnetic wave propagation in non-dispersive or dispersive media, the temporally second-order and spatially fourth-order explicit scheme has been parallelized and is run on GPU with an excellent speedup. We are also aimed to apply our in-house developed high-order structure-preserving Maxwell’s code to predict the specific absorption rate in human head subject to an incident EM wave emitted from a mobile phone that is in operation.
