Stability and conservation properties of transient field simulations using FIT [PDF]
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
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.

Autoformer‐Driven Convolutional Perfectly Matched Layer for 2D HIE‐FDTD Method
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 ...

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 ...

A three‐point compact LOD‐FDTD method for solving the 2D scalar wave equation
Abstract This letter introduces an unconditionally stable finite‐difference time‐domain (FDTD) method, based on the locally one‐dimensional (LOD) technique, for the solution of the two‐dimensional scalar wave equation (WE) in homogeneous media. The second spatial derivatives in the WE are discretized by using a three‐point compact (implicit) finite ...

An Unconditionally Stable Cylindrical FDTD Method to Analyze the EM Ground Wave Propagation
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 ...

Extended ADI‐FDTD for anisotropic magnetised graphene sheets
The unconditionally stable alternating‐direction‐implicit finite‐difference time‐domain (ADI‐FDTD) method is extended for modelling anisotropic magnetised graphene sheets. In contrast to the conventional method for isotropic media, two additional sub‐stepping calculations are applied to incorporate anisotropic medium properties.
