Application of FPGA technology to accelerate the finite-difference time-domain (FDTD) method

Proceedings of the 2002 ACM/SIGDA tenth international symposium on Field-programmable gate arrays - FPGA '02, 2002
The continuing advances in the field of electrical engineering, in areas like cellular communications, fiber optics, mobile and multi-gigahertz electronics have necessitated a computer-assisted design approach to the complex electromagnetic interactions and problems that arise.

Design of optimum terahertz transient response using finite-difference time-domain (FDTD) method

Conference Proceedings. LEOS'98. 11th Annual Meeting. IEEE Lasers and Electro-Optics Society 1998 Annual Meeting (Cat. No.98CH36243), 1998
Summary form only given. The efficient generation of high intensity and high bandwidth terahertz radiation using photoconductive antenna has attracted lots of interest for terahertz imaging. Increasing the static field at the point of optical-pulse illumination between the photoconductive gap has enhanced the intensity of the terahertz radiation ...

Appendix C. The finite-difference time-domain (FDTD) method

2018
The simulations used in this work were all done using the finite-difference timedomain (FDTD) method. One of a fairly large number of methods and variations on methods applicable to the simulation of electromagnetic fields, the FDTD is particularly simple and intuitive, and its application is well adapted to computation of high-frequency ...

Modeling of microwave ring resonators using the finite-difference time-domain method (FDTD)

Microwave and Optical Technology Letters, 2000
Scattering parameters of microstrip ring resonators (with and without slits) that are either edge or side coupled to the feedlines are simulated by the FDTD method. The strip conductors on the device can either be infinitely thin or finite in thickness. The simulations predict the occurrence of resonance peak splitting due to the simultaneous existence

A comparison of finite difference time-domain (FDTD) and transmission-line modeling (TLM) methods

Proceedings of the IEEE SoutheastCon 2000. 'Preparing for The New Millennium' (Cat. No.00CH37105), 2002
This paper presents both theoretical and qualitative comparison of the two most popular time-domain numerical methods for the analysis of electromagnetic problems: the transmission-line modeling (TLM) method and the finite-difference time-domain (FDTD). The comparison is based on the author's experience as well as others.

Far‐field pattern calculation in body‐of‐revolution finite‐difference time‐domain (BOR–FDTD) method

Microwave and Optical Technology Letters, 2001
AbstractIn this paper, we present a far‐field pattern calculation technique in the body‐of‐revolution finite‐difference time‐domain (BOR–FDTD) method. Because the BOR–FDTD solves two‐ and half‐dimensional problems, it has different features from the three‐dimensional FDTD method in the far‐field pattern calculation.

Printability of opaque and clear phase defects using the finite-difference time-domain (FDTD) method

SPIE Proceedings, 2003
The defect printability for two types of patterns isolated lines and contact holes was studied through a finite-difference time-domain (FDTD) computer simulation approach at the EUV wavelength of 13.5 nm. A three-dimensional FDTD solver was employed for aerial image analysis to assess the overall acceptable defect size for both opaque as well as clear ...

A new hybrid method combination of the finite difference time domain (FDTD) and the method of moments in the time domain (MoMTD)

1998 IEEE EMC Symposium. International Symposium on Electromagnetic Compatibility. Symposium Record (Cat. No.98CH36253), 2002
A hybrid method that efficiently combines two powerful numerical techniques, i.e. the finite difference time domain (FDTD) and the method of moments in the time domain (MoMTD) is presented. The method is applicable to complex geometrics comprising thin wires which are studied using the MoMTD, and arbitrary inhomogeneous dielectric structures analyzed ...
