Geometrically Stochastic Finite Difference Time Domain Method
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019This paper presents a geometrically stochastic finite difference time domain (GS-FDTD) method which inserts the geometrical uncertainty directly into the FDTD method by using the delta method approximation. 1D GS-FDTD equations are derived and used to assess the impact of tissue size variation in a layered biological tissue as a bioelectromagnetic ...

Robust Finite Difference Time Domain Modeling Interface
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2009, 2009Three dimensional finite difference time domain modeling (FDTD) has been used for many years in engineering and Earth science applications. The earlier versions were fraught with problems and limitations, including an inability to be used for modeling a broad range of frequencies, difficulty modeling large physical property contrasts between grid cells,

Finite-difference time domain acoustic-wave algorithm
Il Nuovo Cimento D, 1998A time domain numerical procedure is presented for a simulation of acoustic-wave phenomena. The technique is an adaptation of the finite-difference time domain (FDTD) approach usually applied to model electromagnetic waves. Simple illustrations of propagation in a nondissipative, infinite, homogeneous medium are provided. In scattering by a soft target

The Finite-Difference Time-Domain Method
2012The finite-difference time-domain (FDTD) scheme is one of the most popular computational methods for microwave problems; it is simple to program, highly efficient, and easily adapted to deal with a variety of problems. The FDTD scheme is typically formulated on a structured Cartesian grid and it discretizes Maxwell’s equations formulated in the time ...

Finite-difference time-domain of HF antennas
Proceedings of MILCOM '94, 2002Although there has been extensive research and application of the finite-difference time-domain (FDTD) method to electromagnetic scattering and penetration problems, only recently has FDTD been used to predict the radiation characteristics of antennas. The FDTD method has not been applied to low frequency or electrically small radiating structures. The

The Finite-Difference Time-Domain Method
1998The Finite-Difference Time-Domain (FDTD) method provides a direct integration of Maxwell’s time-dependent equations. During the past decade, the FDTD method has gained prominence amongst numerical techniques used in electromagnetic analysis. Its primary appeal is its remarkable simplicity.

Finite-difference time-domain diakoptic strategies
CEM'11 Computational Electromagnetics International Workshop, 2011In many applications, it may be advisable to "tear apart" the computational domain into several sub-domains separated by "seams," each one treated separately. The sub-domains are then sewn back together at appropriate stages of the computation. We present three main diakoptic strategies, as described below.

Implicit nonstaggered finite‐difference time‐domain method
Microwave and Optical Technology Letters, 2005AbstractA new, unconditionally stable, implicit nonstaggered finite‐difference time‐domain (INS‐FDTD) method is introduced. This method is more efficient than the (unconditionally stable) finite‐element time‐domain (FETD) method with brick elements because the number of nonzero elements in the system matrix is reduced.
