Abstract

Analyzing the electromagnetic (EM) scattering properties of high-speed moving objects is a hot research topic in recent years. However, EM calculations for high-speed moving targets always involve challenges of high computational complexity and low computational efficiency. In this paper, we integrate the Message Passing Interface (MPI) based parallel finite difference time domain (FDTD) method and Lorentz transformation to calculate the EM scattering of a moving metal sphere coated with time-varying plasma. Subsequently, by comparing the outcomes of the proposed Parallel FDTD approach with the serial computing results, the validity of the Parallel FDTD method is validated. Additionally, for a moving and time-varying plasma sheath coated object, the impacts of the time-varying parameters and plasma parameters on the EM scattering properties are investigated using the Parallel FDTD approach. The results indicated that the MPI-Based Parallel FDTD approach displays almost identical precision as the serial approach. Furthermore, the Parallel FDTD approach can enhance computation speed and significantly reduce the computation time.
