Comparison of Taylor finite difference and window finite difference and their application in FDTD

Journal of Computational and Applied Mathematics, 2006
AbstractThe finite difference time domain (FDTD) method is an important tool in numerical electromagnetic simulation. There are many ways to construct a finite difference approximation such as the Taylor series expansion theorem, the filtering theory, etc. This paper aims to provide the comparison between the Taylor finite difference (TFD) scheme based
