Abstract: A three-dimensional electromagnetic particle-in-cell (PIC) simulation code is investigated and developed based on JADLib, an advanced data model library. This work provides preparation for the high-performance computation of PIC simulation with unified data interface. The detailed considerations and methods for design and realization of this code are given. Various typical microwave devices are simulated by using this code. The results show that it is an efficient and practical way for the investigation of PIC simulation.
