Modelling electromagnetic radiation from digital electronic systems by means of the finite difference time domain method [PDF]
, 1992 The necessity for the control and minimisation of unintentional electromagnetic emissions from electrical systems has long been appreciated and much skilled effort is spent on EMI suppression.Due to the complexity of the problem, however, very little in ...

Finite-Difference Time-Domain Simulations
, 2021 This work discusses the Finite-Difference Time-Domain (FDTD) technique to simulate an electromagnetic wave assuming one, two and three dimensions. The propagation medium is assumed to be a free space bounded by two absorbing boundaries, perfect matched layer (PML) and perfect electric conductor (PEC).

Effects of sources on time-domain finite difference models [PDF]
The Journal of the Acoustical Society of America, 2014 Recent work on excitation mechanisms in acoustic finite difference models focuses primarily on physical interpretations of observed phenomena. This paper offers an alternative view by examining the properties of models from the perspectives of linear algebra and signal processing.

Finite-difference time-domain modelling of photonic crystal structures [PDF]
Proceedings of 2001 3rd International Conference on Transparent Optical Networks (IEEE Cat. No.01EX488), 2002 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 (

Subcell Treatment of Sloped Interfaces between Debye Materials in the FDTD Method
Journal of Amasya University the Institute of Sciences and Technology, 2020 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]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2018 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 ...

Finite difference time domain simulation for the brass instrument bore [PDF]
The Journal of the Acoustical Society of America, 2013 In this article, interleaved finite difference time domain methods are developed for the purpose of simulating the dynamics of the acoustic bore, using, as a starting point, an impedance formulation of wave propagation in an acoustic tube; attention is focused here on modeling of viscothermal and radiation losses in the time domain.
