ADI-MRTD Algorithm for Periodic Structures Analysis

International Journal of Antennas and Propagation, 2018
In this paper, a novel algorithm based on the alternating direction implicit (ADI) multiresolution time-domain (MRTD) method for periodic structure simulation is proposed.

Efficient Frequency-Dependent Newmark-Beta-FDTD Method for Periodic Grating Calculation

IEEE Photonics Journal, 2016
In this paper, the Newmark-Beta algorithm is introduced into the finite-difference time-domain (FDTD) method in dispersion media, resulting in an unconditionally stable method for periodic metallic grating analysis.

Two-step Lax–Friedrichs method

Applied Mathematics Letters, 2005
AbstractThe usual Lax–Friedrichs (LxF) method is not dissipative, but we show that a simple variant called the two-step LxF method is dissipative.

On the Discontinuous Galerkin Method for Friedrichs Systems in Graph Spaces [PDF]

, 2006
Solutions of Friedrichs systems are in general not of Sobolev regularity and may possess discontinuities along the characteristics of the differential operator. We state a setting in which the well-posedness of Friedrichs systems on polyhedral domains is ensured, while still allowing changes in the inertial type of the boundary.

Crack path estimation in the shot-earth 772 by a discrete element method [PDF]

, 2022
In the present paper, the fracture behaviour of the shot-earth 772, in terms of crack path, is numerically investigated. To such an aim, a version of the lattice discrete element method is used to numerically simulate fracture toughness testing performed,

A Precise-Integration Time-Domain Formulation Based on Auxiliary Differential Equation for Transient Propagation in Plasma

IEEE Access, 2020
The electromagnetic wave propagation through plasma medium is one of the most important research fields in computational electromagnetics. A numerical formulation based on both the auxiliary differential equation (ADE) and the precise-integration time ...
