Dispersive properties of high order nedelec/edge element approximation of the time-harmonic Maxwell equations

open access: yes, 2004
The dispersive behaviour of high-order Næ#169;dæ#169;lec element approximation of the time harmonic Maxwell equations at a prescribed temporal frequency ω on tensor-product meshes of size h is analysed.

Gauss’ law for moving charges from first principles

open access: yesResults in Physics, 2019
A new suggestion for the derivation of Maxwell’s electromagnetic theory is presented, based on relatively few apriori axioms. We can derive Maxwell’s equations by building on the insight that the relationship between an electric dipole and an electric ...

Simulation of the Finite-Difference Time-Domain (FDTD) Method in 2-Dimensional Electromagnetic Wave Propagation in Absorption Media

open access: yesJurnal Fisika Flux, 2022
This research reviewed Maxwell’s equations and Numerical Discretization using the Finite Difference Time Dependent (FDTD) method. First, Maxwell’s equations are introduced in a linear dielectric medium for 1-dimensional and 2-dimensional configurations ...

The stationary Maxwell–Dirac equations [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2003
The Maxwell-Dirac equations are the equations for electronic matter, the "classical" theory underlying QED. In this article we examine the stationary Maxwell-Dirac equations under weak regularity and decay assumptions. We prove that: There are no embedded eigenvalues in the essential spectrum, $-m\leq E\leq m$.

Optimized Schwarz methods for Maxwell's equations

open access: yes, 2009
Over the last two decades, classical Schwarz methods have been extended to systems of hyperbolic partial differential equations, using characteristic transmission conditions, and it has been observed that the classical Schwarz method can be convergent ...

The physical basis of ionospheric electrodynamics [PDF]

open access: yesAnnales Geophysicae, 2012
The conventional equations of ionospheric electrodynamics, highly succesful in modeling observed phenomena on sufficiently long time scales, can be derived rigorously from the complete plasma and Maxwell's equations, provided that appropriate limits ...

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Maxwell's demon through the looking glass [PDF]

open access: yes, 2007
Mechanical Maxwell's demons, such as Smoluchowski's trapdoor and Feynman's ratchet and pawl need external energy source to operate. If you cease to feed a demon the Second Law of thermodynamics will quickly stop its operation. Nevertheless, if the parity

Evaluating Energy Absorption Performance of Filled Lattice Structures

open access: yesAdvanced Engineering Materials, EarlyView.
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...
