Modeling of microwave ring resonators using the finite-difference time-domain method (FDTD)
Microwave and Optical Technology Letters, 2000Scattering 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), 2002This 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.

IEEE Transactions on Antennas and Propagation, 1997
The finite-difference time-domain (FDTD) and its current generalizations have been demonstrated to be useful and powerful tools for the calculation of the radar cross section (RCS) of complicated objects, the radiation of antennas in the presence of other structures, and other applications.

The efficient modeling of thin material sheets in the finite-difference time-domain (FDTD) method
IEEE Transactions on Antennas and Propagation, 1992A subcell model is presented for including thin material sheets in the finite-difference time-domain method. The subcell model removes the normal restriction which sets the spatial grid increment at least as small as the smallest physical feature in the solution space.

Far‐field pattern calculation in body‐of‐revolution finite‐difference time‐domain (BOR–FDTD) method
Microwave and Optical Technology Letters, 2001AbstractIn 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, 2003The 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 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 ...

The Finite-Difference Time-Domain (FDTD) method is often a viable alternative to other computational methods used for the design of sub-wavelength components of photonic devices. We describe an FDTD based grid refinement method, which reduces the computational cell size locally, using a collection of nested rectangular grid patches.
