Reduced Splitting Error in the Adi-fdtd Method Using Iterative Method
In this study, a new method is introduced to reduce the splitting error in the ADI-FDTD method using iterative method. The proposed method includes two procedures. First we solve the procedure of ADI-FDTD method and secondly a new iterative scheme is adopted. The improvement of reduced splitting error is investigated by numerical examples. © 2008 Wiley Periodicals, Inc. Microwave Opt Technol Le...
متن کاملUnified Efficient Fundamental Adi-fdtd Schemes for Lossy Media
This paper presents the unified efficient fundamental alternating-direction-implicit finite-difference time-domain (ADIFDTD) schemes for lossy media. The schemes presented include averaging, forward-forward, forward-backward and novel exponential time differencing schemes. Unifications of these schemes in both conventional and efficient fundamental forms of source-incorporated ADIFDTD are provi...
متن کاملUnconditionally Stable Leapfrog Adi-fdtd Method for Lossy Media
This paper presents an unconditionally stable leapfrog alternating-direction-implicit finite-difference time-domain (ADIFDTD) method for lossy media. Conductivity terms of lossy media are incorporated into the leapfrog ADI-FDTD method in an analogous manner as the conventional explicit FDTD method since the leapfrog ADI-FDTD method is a perturbation of the conventional explicit FDTD method. Imp...
متن کاملThe Adi-fdtd Method including Lumped Net- Works Using Piecewise Linear Recursive Con- Volution Technique
The lumped network alternating direction implicit finite difference time domain (LN-ADI-FDTD) technique is proposed as an extension of the conventional ADI-FDTD method in this paper, which allows the lumped networks to be inserted into some ADI-FDTD cells. Based on the piecewise linear recursive convolution (PLRC) technique, the current expression of the loaded place can be obtained. Then, subs...
متن کاملFull-wave Semiconductor Devices Simula- Tion Using Adi-fdtd Method
This paper describes the alternating-direction implicit finite-difference time-domain (ADI-FDTD) method for physical modeling of high-frequency semiconductor devices. The model contains the semiconductor equations in conjunction with the Maxwell’s equations which describe the complete behavior of highfrequency active devices. Using ADI approach leads to a significant reduction of the full-wave ...
