Implementation of ADI-FDTD subgrids in ground penetrating radar FDTD models

Journal of Applied Geophysics, 2009
Abstract Realistic numerical modeling of ground penetrating radar (GPR) using the finite-difference time-domain (FDTD) method could greatly benefit from the implementation of subgrids – supporting finer spatial resolution – into the conventional FDTD mesh.

Application of system identification technique to FDTD and FDTD Diakoptics method

23rd European Microwave Conference, 1993, 1993
The system identification technique is applied to the FDTD Diakopties method. The computational time and computer storage are significantly reduced. This technique is successfully used in the FDTD Diakoptics simulation of active microwave circuits.

A hybrid FDTD and leapfrog ADI-FDTD method with PML implementation

2011 IEEE MTT-S International Microwave Symposium, 2011
In this paper, a hybrid FDTD and leapfrog alternating-direction-implicit finite-difference time-domain (ADI-FDTD) method is presented. The perfectly matched layer (PML) absorbing boundary conditions are also incorporated in the method and non-uniform grids are deployed to efficiently model electromagnetic radiation and scattering in open domains.

Advanced FDTD Applications

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, 2008
In 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, 2010
In 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

Single ogive FDTD modeling

2010 The 2nd Conference on Environmental Science and Information Application Technology, 2010
In order to solve the FDTD modeling problem which appears in numerical computation of single ogive about electromagnetic scattering characteristic with the method of Finite Difference Time Domain - FDTD, the FDTD modeling of single ogive is designed, which is based on the analytic function.

Hybridizing DGTD and FDTD

2007 International Conference on Electromagnetics in Advanced Applications, 2007
This paper describes a hybrid combination of FDTD and DGTD employing DGTD only to accurately model the geometric details of curved objects, while maintaining the simplicity of FDTD for the surrounding space.
