Novel Scheme for GPU-Accelerated Finite-Difference Time-Domain
Simulation of Electromagnetic Wave Interaction with Magnetic Plasma
Abstract
Based on graphical processing unit acceleration, a new method of
finite-difference time-domain scheme is proposed to simulate the
interaction between electromagnetic waves and magnetized plasma in
two-dimensional conditions. In this study, transversely electric and
transversely magnetic are computed in time to avoid matrix operations
involving Lorentz equations of motion. Compared to Young’s method, the
new method reduces addition and multiplication by about 63% and 66%,
respectively. The simulation results of ionospheric wave propagation
show that the new method agrees well with Young’s method and the
calculation speed is improved significantly.
