UNCONDITIONALLY STABLE LEAPFROG ADI-FDTD METHOD FOR LOSSY MEDIA [PDF]
Progress In Electromagnetics Research M, 2012 This paper presents an unconditionally stable leapfrog alternating-direction-implicit flnite-difierence time-domain (ADI- FDTD) method for lossy media. Conductivity terms of lossy media are incorporated into the leapfrog ADI-FDTD method in an anal- ogous manner as the conventional explicit FDTD method since the leapfrog ADI-FDTD method is a ...

ADI-FDTD algorithm in curvilinear co-ordinates
Electronics Letters, 2005 The alternating direction implicit (ADI) scheme has been successfully applied to the finite-difference time-domain (FDTD) method to achieve an unconditionally stable algorithm. The ADI-FDTD method is extended to the curvilinear co-ordinate system to form an alternating direction implicit nonorthogonal FDTD (ADI-NFDTD) method. The numerical results show

UNIFIED EFFICIENT FUNDAMENTAL ADI-FDTD SCHEMES FOR LOSSY MEDIA [PDF]
Progress In Electromagnetics Research B, 2011 This paper presents the unifled e-cient fundamen- tal alternating-direction-implicit flnite-difierence time-domain (ADI- FDTD) schemes for lossy media. The schemes presented include aver- aging, forward-forward, forward-backward and novel exponential time difierencing schemes. Uniflcations of these schemes in both conven- tional and e-cient fundamental

Efficient solution on solving 3D Maxwell equations using stable semi-implicit splitting method
AIP Advances, 2016 In this paper, we propose an efficient solution on solving 3-dimensional (3D) time-domain Maxwell equations using the semi-implicit Crank-Nicholson (CN) method for time domain discretization with advantage of unconditional time stability. By applying the

Complexity, Volume 2019, Issue 1, 2019., 2019 Accurate forward modeling is of great significance for improving the accuracy and speed of inversion. For forward modeling of large sizes and fine structures, numerical accuracy and computational efficiency are not high, due to the stability conditions and the dense grid number.
