Abstract :
In this paper, we have introduced a basic two-dimensional finite difference time-domain (2D-FDTD) method with TM and TE modes, and developed a model of antipodal extremely low frequency (ELF) wave propagation on the Schumann resonances (SR) of the earth. We have used an advanced algorithm, which is combining the grid-cells approaching to the certain pole points, and have improved the numerical stability and efficiency compared with those of the original basic algorithm.
