Subcell Treatment of Sloped Interfaces between Debye Materials in the FDTD Method
This paper presents the application of the subcell technique for the treatment of sloped interface in finite-difference time-domain method. The technique is based on the averaging of permittivities in each cell crossed by the material interface.

FDTD Analysis of Electromagnetic Wave Propagation in an Inhomogeneous Ionosphere under Arbitrary-Direction Geomagnetic Field [PDF]
The finite-difference time-domain (FDTD) model was developed to analyze electromagnetic (EM) wave propagation in an inhomogeneous ionosphere. The EM analysis of ionosphere is complicated, owing to various propagation environments that are significantly ...

Application of finite-difference time domain and dynamic differential evolution for inverse scattering of a two-dimensional perfectly conducting cylinder in slab medium [PDF]
[[abstract]]We apply the dynamic differential evolution (DDE) algorithm to solve the inverse scattering problem for which a two-dimensional perfectly conducting cylinder with unknown cross section is buried in a dielectric slab medium.

Simulations of solar cell absorption enhancement using resonant modes of a nanosphere array [PDF]
We propose an approach for enhancing the absorption of thin-film amorphous silicon solar cells using periodic arrangements of resonant dielectric nanospheres deposited as a continuous film on top of a thin planar cell.

Finite-difference time-domain simulation of spacetime cloak
In this work, we present a numerical method that remedies the instabilities of the conventional FDTD approach for solving Maxwell's equations in a space-time dependent magneto-electric medium with direct application to the simulation of the recently proposed spacetime cloak.

Finite-difference time-domain modelling of photonic crystal structures [PDF]
The usual, highly efficient, modelling tools for planar optical devices are generally not suitable for modelling photonic crystal structures. For example, the beam propagation method fails when applied to these strongly scattering structures since presumptions are made on the propagation direction of the waves. The finite-difference time-domain method (

Finite-difference time-domain simulation of partial discharges in a gas insulated switchgear
It is important to estimate the current magnitude and charge amount of a partial discharge (PD) in a gas-insulated switchgear (GIS). In this study, electromagnetic fields generated by a PD in an 84 kV-class three-phase GIS for testing have been measured ...

Electromagnetic modelling of a monolithic pulse reshaper based on a photonic crystal waveguide integrated with a SOA [PDF]
Finite difference time domain (FDTD) and finite element (FE) frequency domain methods are used to study the propagation of arbitrary chirped pulses in photonic crystal (PhC) waveguide.

A multi-domain hybrid method for head-on collision of black holes in particle limit
A hybrid method is developed based on the spectral and finite-difference methods for solving the inhomogeneous Zerilli equation in time-domain. The developed hybrid method decomposes the domain into the spectral and finite-difference domains.

A novel high accuracy finite-difference time-domain method
The finite-difference time-domain (FDTD) method is widely used for numerical simulations of electromagnetic waves and acoustic waves. It is known, however, that the Courant condition is restricted in higher dimensions and with higher order differences in
