International Journal of Antennas and Propagation, Volume 2019, Issue 1, 2019., 2019 Ground penetrating radar (GPR), as a kind of fast, effective, and nondestructive tool, has been widely applied to nondestructive testing of road quality. The finite‐difference time‐domain method (FDTD) is the common numerical method studying the GPR wave propagation law in layered structure.

Stability and conservation properties of transient field simulations using FIT [PDF]
Advances in Radio Science, 2003 Time domain simulations for high-frequency applications are widely dominated by the leapfrog timeintegration scheme. Especially in combination with the spatial discretization approach of the Finite Integration Technique (FIT) it leads to a highly ...

Parallelization of Faber Polynomial Based Propagators for Laser Applications
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 38, Issue 4, July/August 2025.ABSTRACT In order to simulate a laser system, the evaluation of a complex semilinear master equation is needed, including the description of the wave propagation by Maxwell's equations and appropriate rate equations. The denser the spatial discretization, the slower the computation time of the time‐dependent propagator.

Accuracy limitations of the locally one-dimensional FDTD technique [PDF]
, 2014 While the alternating-direction implicit finite-difference time-domain (ADI-FDTD) method preserves the second-order temporal accuracy of the conventional FDTD technique, the locally one-dimensional (LOD)-FDTD method exhibits a first-order in time ...

Autoformer‐Driven Convolutional Perfectly Matched Layer for 2D HIE‐FDTD Method
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.The Autoformer neural network is introduced to replace the conventional multi‐layer CPML structure. This method markedly improves computational efficiency while maintaining excellent wave absorption performance. ABSTRACT An innovative deep‐learning driven convolutional perfectly matched layer (CPML) integrated into the hybrid implicit‐explicit finite ...

International Journal of Antennas and Propagation, Volume 2018, Issue 1, 2018., 2018 We propose an efficient finite difference time domain (FDTD) method based on the piecewise linear recursive convolution (PLRC) technique to evaluate the human body exposure to electromagnetic (EM) radiation. The source of radiation considered in this study is a high‐power antenna, mounted on a military vehicle, covering a broad band of frequency (100 ...

Viability of Numerical Full-Wave Techniques in Telecommunication Channel Modelling [PDF]
, 2020 In telecommunication channel modelling the wavelength is small compared to the physical features of interest, therefore deterministic ray tracing techniques provide solutions that are more efficient, faster and still within time constraints than current ...

An Unconditionally Stable Cylindrical FDTD Method to Analyze the EM Ground Wave Propagation
International Journal of Antennas and Propagation, Volume 2018, Issue 1, 2018., 2018 We extended the unconditionally stable associated Hermite (AH) FDTD method to the cylindrical coordinate system for analyzing the electromagnetic (EM) ground wave propagation. With AH domain differentiate operator technology and paralleling‐in‐order solution scheme, the cylindrical time‐domain Maxwell equations with complex frequency shifted perfectly ...
