The study of 3D FDTD modelling of large-scale Bragg gratings validated by experimental measurements
JPhys PhotonicsThis study discusses the importance of accurately calculating the optical response of Bragg gratings and the challenges associated with the 3D finite-difference time-domain (FDTD) method for simulating large-scale structures. The Bragg grating section in

Time domain scattering and radar cross section calculations for a thin, coated perfectly conducting plate [PDF]
Radar cross section (RCS) calculations for flat, perfectly conducting plates are readily available through the use of conventional frequency domain techniques such as the Method of Moments (MOM).

, 2015 Solar cells provide a renewable and clean energy by converting the sunlight to electricity. However, it is important to reduce the cost of the solar cell and increase the efficiency in order to be considered as a reliable energy source. In this work, a theoretical analysis for a waveguide structure by using Finite Difference (FD) methods is presented ...

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.

Ferrite analysis using the finite‐difference time‐domain (FDTD) method
Microwave and Optical Technology Letters, 1992AbstractThis article introduces a new method for analyzing ferrite structures. This method is implemented in a FDTD algorithm; then the computation is directly made in the time domain. An application in the particular case of a two‐dimensional problem is presented.

A distributed implementation of the finite difference time‐domain (FDTD) method
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1995AbstractThe finite difference time‐domain (FDTD) method is a well known numerical technique that has been used to solve electromagnetic boundary value problems. However, the method requires large computational resources to solve a problem, restricting its use on sequential computers to small problems.This has led to the use of expensive supercomputers ...

Optical disk structure analysis with finite-difference time domain (FDTD) method
SPIE Proceedings, 2003A method of high-density optical disk structure design using computational electromagnetic FDTD analysis is proposed. A staircase method is used to simulate the realistic sidewall geometrical structure of the land-groove of phase-change optical disk. The phase-change materials appear as different optical characteristics under irradiation of different ...

MR/FDTD: A multiple-region finite-difference--time-domain method
Microwave and Optical Technology Letters, 1997Multiple-region FDTD (MR/FDTD), an extension of classical FDTD to multiple subregions within a problem domain, is introduced. In MR/FDTD the problem domain is broken into several independent FDTD subregion lattices. The subregions lattices are terminated with the use of a surface integrated radiation boundary condition applied simultaneously to all ...

A novel separable backward-central finite difference time domain (FDTD) method
2005 IEEE Antennas and Propagation Society International Symposium, 2005In this paper, we present a novel, separable, backward-central FDTD (SBC-FDTD) method in which both the backward and central differencing are employed to discretize the time and spatial derivatives of the Maxwell's equations. For the type of problems in which the FDTD cell size in one direction is much smaller than those along the other directions, the
