Alternating-direction implicit (adi) formulation of the finite-difference time-domain (fdtd) method: algorithm and material dispersion implementation

IEEE Transactions on Electromagnetic Compatibility, 2003
The alternating-direction implicit finite-difference time-domain (ADI-FDTD) technique is an unconditionally stable time-domain numerical scheme, allowing the /spl Delta/t time step to be increased beyond the Courant-Friedrichs-Lewy limit. Execution time of a simulation is inversely proportional to /spl Delta/t, and as such, increasing /spl Delta/t ...

Numerical analysis of high frequency GaAs FET transistor using alternating direction implicit (ADI) finite-difference time-domain method; Distributed modeling approach

AEU - International Journal of Electronics and Communications, 2021
Abstract The unconditionally stable ADI Finite Difference Time Domain (FDTD) method is used to govern the distributed model equations of high frequency GaAs FET transistor. This implicit scheme with no constraint by a stability criterion is exploited to increase the time performance of the CPU time considerably compared with the conditionally stable ...

Vectorized Directional Sweep Based Parallelization Method for Factored Alternating Direction Implicit (ADI) Schemes

International Journal of Computational Fluid Dynamics, 1998
Abstract A new parallelization method is proposed for factored alternating direction implicit (ADI) schemes based on the vectorized global domain directional sweep. This approach, when combined with multi-partitioning domain decomposition, significantly reduces the frequency of necessary communication calls and minimizes processor idling during the ...

Application of Alternating Direction Implicit (ADI) Algorithm to Staggered-grid PSTD Modeling of Electromagnetic Waves

PIERS Online, 2010
By applying the fast Fourier transform (FFT) and inverse transform to represent the spatial derivatives, the pseudo-spectral time-domain (PSTD) method has achieved a spatial grid of only two points per wavelength while maintaining a high accuracy. Its computational speed can be further accelerated by applying alternating-direction implicit (ADI), which

Computational acceleration of image inpainting Alternating-Direction Implicit (ADI) method using GPU CUDA

2017 International Conference on Control, Electronics, Renewable Energy and Communications (ICCREC), 2017
This paper presents a computational acceleration of image inpainting using parallel processing based on Graphics Processing Unit (GPU) Compute Unified Device Architecture (CUDA). We use parabolic partial differential equation (PDE) called heat equation as the model equation.

A new method for simulation of on-chip interconnects and substrate currents with 3D alternating-direction-implicit (ADI) Maxwell solver

International Conference on Simulation of Semiconductor Processes and Devices, 2003. SISPAD 2003., 2003
We introduce a time-domain method to simulate the digital signal propagation along on-chip interconnects by solving Maxwell's equations with the Alternating-Direction-Implicit (ADI) method. With this method, we are able to resolve the large scale (i.e. on-chip electromagnetic wave propagation) and fine scale (i.e.

Modeling RF Signal Propagation Along On-Chip Interconnects and the Effect of Substrate Doping with the Alternating-Direction-Implicit Finite-Difference Time-Domain (ADI-FDTD) Method

Conference Record of the 2006 Twenty-Seventh International Power Modulator Symposium, 2006
The Alternating-Direction-Implicit Finite-Difference Time-Domain (ADI-FDTD) method is used to analyze Metal-Insulator-Semiconductor-Metal interconnects by solving Maxwell's equations in the time domain. This analysis shows that the silicon substrate losses and the metal line losses can be modeled with high resolution.
