Comparison between HIE-FDTD method and ADI-FDTD method

Microwave and Optical Technology Letters, 2007
AbstractThis letter gives the comparison of the 3D hybrid implicit–explicit finite‐difference time‐domain (HIE‐FDTD) method with the ADI‐FDTD method through numerical examples. It shows that the HIE‐FDTD method has higher accuracy than the ADI‐FDTD method, especially for larger rate of field variation; the time step size, which has a detrimental effect

Accuracy improved ADI‐FDTD methods

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2006
AbstractFDTD method plays an important role for simulation of different structures in various fields of engineering, such as RF/microwaves, photonics and VLSI. However, due to the CFL stability constraint, the FDTD time step is still small and the related CPU time is still large for modelling fine geometry where small cell sizes are required to resolve

Stability analysis for the AIBO‐FDTD method

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 2008
AbstractThe stability of the implicit finite‐difference time‐domain (FDTD) method named alternating implicit block overlapped (AIBO) FDTD is presented in this paper. Based on separation of variables method, the spectral radius of the growth matrix for AIBO‐FDTD is obtained.
