Parallel FDTD modelling of nonlocality in plasmonics [PDF]
IEEE Transactions on Antennas and Propagation, 2020 As nanofabrication techniques become more precise, with ever smaller feature sizes, the ability to model nonlocal effects in plasmonics becomes increasingly important. While nonlocal models based on hydrodynamics have been implemented using various computational electromagnetics techniques, the finite-difference time-domain (FDTD) version has remained ...

The CGM and the FDTD for SAR studies [PDF]
Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting, 2002 In the study of electromagnetic radiation effects over dielectric bodies, effective numerical methods are needed. At present, there is a lack of tools for measuring these effects and due to the huge growth of microwave devices, like cellular radio telephones working close to the human body, it is necessary to develop accurate numerical methods for ...

Transient FDTD simulation validation [PDF]
2010 IEEE International Symposium on Electromagnetic Compatibility, 2010 In computational electromagnetic simulations, most validation methods have been developed until now to be used in the frequency domain. However, the EMC analysis of the systems in the frequency domain many times is not enough to evaluate the immunity of current communication devices.

FDTD modelling of reverberation chamber
Electronics Letters, 2005 The finite-difference time-domain (FDTD) method is applied to the simulation of a reverberation chamber. The real losses of the reverberation chamber are taken into account in a post-treatment process. The predicted results are compared with measured data and good agreement is reported.

A Stable FDTD Method with Embedded Reduced-Order Models [PDF]
in IEEE Transactions on Antennas and Propagation, vol. 66, no. 2,
pp. 827-837, Feb. 2018, 2016 The computational efficiency of the Finite-Difference Time-Domain (FDTD) method can be significantly reduced by the presence of complex objects with fine features. Small geometrical details impose a fine mesh and a reduced time step, significantly increasing computational cost.

An Unconditionally Stable Conformal LOD-FDTD Method For Curved PEC Objects and Its Application to EMC Problems [PDF]
arXiv, 2021 The traditional finite-difference time-domain (FDTD) method is constrained by the Courant-Friedrich-Levy (CFL) condition and suffers from the notorious staircase error in electromagnetic simulations. This paper proposes a three-dimensional conformal locally-one-dimensional FDTD (CLOD-FDTD) method to address the two issues for modeling perfectly ...

High-order FDTD schemes for Maxwell's interface problems with discontinuous coefficients and complex interfaces based on the Correction Function Method [PDF]
, 2021 We propose high-order FDTD schemes based on the Correction Function Method (CFM) for Maxwell's interface problems with discontinuous coefficients and complex interfaces. The key idea of the CFM is to model the correction function near an interface to retain the order of a finite difference approximation. For this, we solve a system of PDEs based on the

Application of GPU-accelerated FDTD method to electromagnetic wave propagation in plasma using MATLAB Parallel Processing Toolbox [PDF]
arXiv, 2022 Since numerical computing with MATLAB offers a wide variety of advantages, such as easier developing and debugging of computational codes rather than lower-level languages, the popularity of this tool is significantly increased in the past decade. However, MATLAB is slower than other languages.

Application of Cross-correlation Greens Function along with FDTD for Fast Computation of Envelope Correlation Coefficient over Wideband for MIMO Antennas [PDF]
, 2016 In this paper, the concept of cross-correlation Green's functions (CGF) is used in conjunction with the finite difference time domain (FDTD) technique for calculation of envelope correlation coefficient (ECC) of any arbitrary MIMO antenna system over wide frequency band.

On the Q-BOR-FDTD method [PDF]
arXiv, 2022 We discuss a recently proposed approach termed Q-BOR-FDTD method and develop its main equations in a clearer and more rigorous way. We show that it is unsuitable for the calculation of the eigenfunctions in the case of degenerate states and propose an improvement to overcome such limitation.
