The propagation of a sinusoidal wave is simulated in a simplified model of two-dimensional (2-D) local ionosphere using a novel implicit auxiliary differential equation (ADE) finite-difference time-domain (FDTD) method combined with a layer smoothing (LS) technique. Impacts of both the diurnal variation and the natural geomagnetic field on the ionosphere model are taken into account. It is found that...
An auxiliary differential equation (ADE) finite-difference time-domain (FDTD) method is applied to analyze the effect of ionospheric high frequency (HF) heating on electromagnetic (EM) wave propagation. First ionosphere background parameters in East China generated from IRI are introduced in the study model and nonlinear phenomenon during ionospheric heating process at low altitude between 60 and...
The extremely low frequency (ELF) electromagnetic (EM) wave propagation parameters are obtained and studied based on the simulated Schumann resonances (SRs). To obtain the SRs, ELF EM wave propagation and EM environment of the Earth-ionosphere (E-I) system are rigorously simulated using the geodesic finite-difference time-domain (FDTD) method. Prony's method is introduced to analyze the simulation...
