In this paper, 2D the pseudo-spectral time domain (PSTD) algorithm is applied to simulate propagation of line-source in each layer of ionosphere, which is used to solve the equations of cold plasma. The excitation source is applied to eliminate Gibbs phenomenon, which is used by a compact wave source condition. The results are significance to propagation of line-source in ionosphere.
In this paper, the stability of the one dimensional (1D) finite-difference time-domain (FDTD) difference scheme for the high power microwave (HPM) atmosphere propagation model is analyzed. The derivation shows that the conventional Courant condition is still valid when the time step meets the constraint imposed by the collision frequency. Our conclusion confirms that the FDTD method is available in...
The finite difference time domain (FDTD) method for solving ionosphere propagation of microwave pulse will waste great time and memory. In this paper, the pseudo-spectral time domain (PSTD) algorithm is applied to simulate propagation of microwave pulse in each layer of ionosphere, which is used to solve the equations of cold plasma. Compared to the FDTD method, the PSTD algorithm is much efficiency...
In this paper, we studied linear coupling function of the ultra-wide-band (UWB) pulse coupled to the computer case with different kinds of slots, apertures and hole arrays by the finite-difference time-domain (FDTD) method combined with fast Fourier transform (FFT) method.
The finite-difference time-domain (FDTD) method is used to analyze the rule of the electromagnetic pulse (EMP) coupled to the computer case with different kinds of slots, apertures and hole arrays. The spectrum of power density in midpoint of case is analyzed and illustrated by fast Fourier transform (FFT) method. The rule of EMP having different incident direction coupled into computer case is discussed...
