Abstract: In the electromagnetism,FDTD which has been widely used in the field of dielectric device's designing can simulate the changes of electromagnetic field in space accurately .With abundant computing resources, many-core pro- cessor can get good adaptability for compute-intensive task. Based on the analysis of Maxwell's ec)uations and the FDTD simulation algorithm,we achieved the parallel algorithm about FDTD. According to the experiment's results,FDTD al- gorithm has high computational efficiency on the platform of many-core processor, and can make full use of the structure characteristic of many-core processor.
Key words: Finite difference time domain(FDTD)，Many-core, Parallel, Optimization
