As a numerical calculation method, finite-difference time-domain method (FDTD), which is used to analyze the electromagnetic problems, can cause some inevitable errors. This paper mainly analyzes the effects of FDTD using different grid length to dispose of the electromagnetic problems. Then, we briefly illustrate the numerical stability condition of FDTD and the relationship between the space-step...
The multiresolution time domain (MRTD) is researched and utilized to analyze the electromagnetic scattering of a target, in order to illustrate its superiorities and advantages. First of all, the paper employs the Daubechies-wavelet, which is compact support, to be the basis, derives the strict calculation formula systematically, while analyzes its dispersion characteristic and the absorbing boundary...
