2007 Workshop on Computational Electromagnetics in Time-Domain, 2007
Many electromagnetic applications can be analyzed using a "standard" FDTD code. However, some applications require special features such as ground interaction, periodic boundary conditions and more advanced excitation sources. This paper presents examples of such applications and references are given to work where descriptions of necessary enhancements

Comparison of FT-FDTD and Spectral Domain FDTD for Periodic Structures
2008 International Workshop on Antenna Technology: Small Antennas and Novel Metamaterials, 2008In recent years, the metamaterials and its applications to antenna and other fields have been widely investigated theoretically and experimentally. The metamaterials are usually realized by some periodic structures composed of a conductor and/or dielectric/magnetic materials.

The SP-FDTD method for high-order FDTD plane wave injection
Proceedings of the 9th International Symposium on Antennas, Propagation and EM Theory, 2010In the paper, the method of splitting plane wave FDTD (SP-FDTD) algorithm, an efficient method of introducing plane wave source into finite difference time domain grids, is presented for solving oblique incident wave for the modified high-order FDTD (M24 scheme). Numerical examples in 2-D demonstrate the valid of the method and normalized field leakage

1993 IEEE MTT-S International Microwave Symposium Digest, 2002
A finite-difference-time-domain (FDTD) diakoptics method is developed. Sequential and parallel algorithms are provided to connect cascaded segments and to realize the modular computation of large circuits. When the large circuit is modified, only a few segments need to be recalculated, while the mutual interaction is preserved.

The FDTD method has gained tremendous popularity in the past decade as a tool for solving Maxwell's equations. It is based on simple formulations that do not require complex asymptotic or Green's functions. Although it solves the problem in time, it can provide frequency-domain responses over a wide band using the Fourier transform.

In the traditional finite difference time domain (FDTD) method, the studied structure is modeled as elementary cells, which sizes have to be small enough to get close to the reality. Then, this discretization is applied to the whole calculation volume, even though some zones do not need such fine discretization. Consequently, this numerical

IEEE Transactions on Antennas and Propagation, 1993
The finite-difference time-domain (FDTD) method easily includes materials with constant values of permittivity and conductivity. However, most lossy dielectrics are described over a band of frequencies by a constant complex permittivity. For a transient FDTD calculation, constant real permittivity and conductivity values provide a poor approximation ...
