Custom hardware implementation of the finite-difference time-domain (FDTD) method
2002 IEEE MTT-S International Microwave Symposium Digest (Cat. No.02CH37278), 2003Finite-Difference Time-Domain (FDTD) Analysis is a very popular method for solving electromagnetic problems. The algorithm is computationally Intensive and simulations can take several days to run on traditional, multiprocessor supercomputer platforms.

Tutorial on finite-difference time-domain (FDTD) methods for room acoustics simulation
The Journal of the Acoustical Society of America, 2021Wave-based simulation models for acoustics have remained an active area of research and development for the past three decades. Wave-based methods aim to solve the 3D wave equation directly and therefore have large computational costs relative to conventional ray-based methods, which tend to simplify wave-diffraction effects.

Transient response of terahertz emitter using finite-difference time-domain (FDTD) method
1998 IEEE Sixth International Conference on Terahertz Electronics Proceedings. THZ 98. (Cat. No.98EX171), 1998The transient response and the radiation pattern of the various terahertz dipole antenna were successfully obtained using FDTD method. As a result, a design guideline was presented for the trade-off between the peak height and the 3-dB bandwidth. In addition, the effect of the electrode shape and the laser beam position on the photoconductive switch ...

Analysis of interconnect lines using the finite‐difference time‐domain (FDTD) method
Microwave and Optical Technology Letters, 2002AbstractIn this Letter the coupling effect (cross talk) in parallel microstrip interconnects is analyzed with the use of the finite‐difference–time‐domain (FDTD) method. The interconnects are terminated either by lumped elements or by a perfectly matched layer (PML), and the results obtained from these two methods are compared. © 2002 Wiley Periodicals,

Wafer 3D effect study with finite difference time domain (FDTD) simulation method
2015 China Semiconductor Technology International Conference, 2015As the technology reaches the 2x nm node in semiconductor manufacture, wafer 3-dimensional topography proximity effects (W3D) becomes more and more challenging during lithography process, especially for the implantation layers. This effect is caused by the light reflection from the substrate during wafer-exposure process, which can cause the linewidth ...

Parallel implementations of the finite difference time domain (FDTD) method
Second International Conference on Computation in Electromagnetics, 1994In this paper different parallel and sequential implementations of the finite difference time domain (FDTD) method are evaluated. The performance of current sequential architectures are first investigated. Possible improved performances from different parallel architectures are then examined.

A new higher-order subgridding method for finite difference time domain (FDTD) algorithm
IEEE Antennas and Propagation Society International Symposium. 1998 Digest. Antennas: Gateways to the Global Network. Held in conjunction with: USNC/URSI National Radio Science Meeting (Cat. No.98CH36194), 2002In this paper the authors present a general subgridding scheme for enhancing the finite difference time domain (FDTD) algorithm. It is different from the conventional approaches in that it does not employ weighted averages of the electric or magnetic fields in the transition zone from the coarse to the fine grid regions, but employs a novel procedure ...

Analysis of frequency selective surfaces using the finite difference time domain (FDTD) method
IEEE Antennas and Propagation Society International Symposium (IEEE Cat. No.02CH37313), 2003While the method of moments (MoM) is well suited for analyzing the thin, planar, patch-type of frequency selective surface (FSS) elements, the same cannot be said for arbitrary elements that have a finite thickness, and are inhomogeneous in nature. We employ a periodic version of the finite difference time domain (FDTD) algorithm to analyze the effect ...
