Bulk Forces and Interface Forces in Assemblies of Magnetized Pieces of Matter

IEEE Transactions on Magnetics

Year: 2016 | Volume: 52, Issue: 3 | Journal Article |

Cited by: Papers (9)

HTML

When two magnets are stuck together, where do magnetic forces operate and which formulas should one apply to compute them? Such frequently asked questions do not find immediate answers in the literature on forces, mainly because the force field is obtained, by the Virtual Power Principle (VPP), as a (mathematical, vector-valued) distribution, not as a plain vector field, which would be more conven...Show More

Forces Between Conductors: The “50/50 Rule” About the Partition of Supplied Energy

IEEE Transactions on Magnetics

Year: 2015 | Volume: 51, Issue: 3 | Journal Article |

HTML

We prove the 50/50 rule of Fig. 1 by a Lagrangian technique (all fields pulled back to the reference configuration at time 0) which exposes the necessity of two circumstances for the result to hold: 1) time-invariance of currents, when expressed in “material form” and 2) equality of (magnetic) coenergy and energy, which excludes nonlinear $\boldsymbol {B}$ – $\boldsymbol {H}$ laws. A dual result...Show More

HTML

In magnetoelastic interactions, the virtual power principle is powerful enough to solve all force problems, but only if the coupled constitutive laws are completely known. We use it to derive force densities in magnetized matter for a few such laws, insisting on the fact that a full knowledge of the magnetic field may not be enough to determine the force density when the local B-H law depends on t...Show More

Discrete Magneto-Elasticity: A Geometrical Approach

IEEE Transactions on Magnetics

Year: 2010 | Volume: 46, Issue: 8 | Journal Article |

Cited by: Papers (12)

HTML

We show that magnetism and elasticity have very similar mathematical structures when fields are considered as differential forms of adequate nature. The same discretization principles and techniques that succeeded in electromagnetism, notably the use of edge elements, then lead to a manageable form of coupled elasto-magnetic problems.Show More

Effective, Frequency-Dependent, Permeability of “Split-Ring” Metamaterials via Homogenization

IEEE Transactions on Magnetics

Year: 2009 | Volume: 45, Issue: 3 | Journal Article |

Cited by: Papers (4)

HTML

Homogenization, which reduces the cost of numerical simulations in materials with repetitive structure, is a promising approach to the design of metamaterials. We justify the procedure by a convergence result and apply it to the case of an array of split rings, where a negative effective permeability can be expected near some resonant frequency. A simplified model confirms this.Show More

Force-Related Nuts and Bolts in the Discretization Toolkit for Electromagnetics

IEEE Transactions on Magnetics

Year: 2008 | Volume: 44, Issue: 6 | Journal Article |

Cited by: Papers (7)

How to deal with motion and forces, at the discrete level, is still an open problem, if we want the coupled discrete dynamical system that results from discretization to behave consistently (energy and momentum conservation, etc.). If discretization is conceived as putting together appropriate pieces of a toolkit, this raises the question of which pieces should correspond to items like Lorentz for...Show More

An efficient technique is proposed for analyzing two- and three-dimensional lossy periodic composite materials, combining an asymptotic multiscale method with the unfolding method. The computed effective conductivities for square cylinders and cubes suspended in a host isotropic medium are compared to the Maxwell-Garnett mixing formula predictions.

Homogenization, which reduces the cost of numerical simulation in materials with repetitive structure, is a promising approach to the design of photonic crystals and metamaterials. But its mathematical foundations may seem daunting. A link with standard harmonic analysis is indicated here ("homogenization as approximate Fourier analysis for lattice group actions"), which should help clarify the is...Show More

Solving a given problem by two "complementary" formulations gives useful bilateral bounds on some quantities. Mixed hybrid methods achieve the same result by solving only one algebraic system and by using two different methods to interpolate from the computed degrees of freedom.Show More

Generating Whitney forms of polynomial degree one and higher

IEEE Transactions on Magnetics

Year: 2002 | Volume: 38, Issue: 2 | Journal Article |

Cited by: Papers (41)

A rationale for Whitney forms is proposed; they are seen as a device to approximate manifolds, with approximation of differential forms as a byproduct. A recursive generating formula is derived. A natural way to build higher-degree forms then follows.Show More

"Stiff" problems in eddy-current theory and the regularization of Maxwell's equations

IEEE Transactions on Magnetics

Large ratios of extreme nonzero conductivities in eddy current problems cause poor conditioning, due to the kernel of the curl-curl operator. Solutions to this problem (wrongly blamed on edge elements by some) are discussed.Show More

Yee-like schemes on staggered cellular grids: a synthesis between FIT and FEM approaches

A. Bossavit;L. Kettunen

IEEE Transactions on Magnetics

Year: 2000 | Volume: 36, Issue: 4 | Journal Article |

Cited by: Papers (107)

We propose an analysis (discretization techniques, convergence) of numerical schemes for Maxwell equations which use two meshes (not necessarily tetrahedral), dual to each other. Schemes of this class generalize Yee's "finite difference in time domain" method (FDTD). We distinguish network equations (the discrete equivalents of Faraday's law and Ampere's relation) which can be set up without any r...Show More

A posteriori error bounds by "local corrections" using the dual mesh

IEEE Transactions on Magnetics

Year: 1999 | Volume: 35, Issue: 3 | Journal Article |

Cited by: Papers (5)

Some EM field problems can be solved in two different, symmetrical ways, which are "complementary" in the sense that each one corrects some deficiencies of the other. In particular, one obtains error bounds this way. Taking as an example the static conduction problem, the authors propose a geometrical presentation of this theory, which generalizes and symmetrizes the classical but a bit forgotten ...Show More

In this paper, some structures which underlie the numerical treatment of second-order boundary value problems are studied using magnetostatics as an example. The authors show that the construction of a discrete Hodge is a central problem. In this light, they interpret finite element techniques as a realization of the discrete Hodge operator in the Whitney complex. This enables one to view the Gale...Show More

In this paper gauging is approached as a problem of selecting a representative in classes of equivalent representations. In this light we interpret how different gauging techniques are related to each other, and examine how they can be imposed on the discrete level using Whitney elements.Show More

In this paper we construct discrete spaces for fields whose curl or div vanishes but for which one cannot find potentials. In electromagnetism such fields appear when the problem domain is not topologically trivial. The discrete spaces are constructed with Whitney elements in simplicial meshes.Show More

A homogenization technique for harmonic Maxwell equations in a composite periodic medium is given. This technique consists in using the finite element method to solve Maxwell equations with adequate periodicity conditions on a "basic cell" of the structure. We describe this "cell problem" and report on numerical results for some cell structures.Show More

"Small parameter" problems in eddy-current theory: a review, and case-study on how to avoid meshing small air-gaps

IEEE Transactions on Magnetics

Year: 1996 | Volume: 32, Issue: 3 | Journal Article |

Cited by: Papers (11)

Perturbation approaches in terms of a small dimensionless parameter are standard and very useful in field computations. For instance, if the width of an airgap can be considered "small", no mesh inside the gap will be required. However, it often happens that two such small parameters intervene in the modelling, and "compete" in some way. In such situations, two, very different, limit problems are ...Show More

Cited by: Papers (3)

We show how to pass from the local Bean's model, assumed to be valid as a behavior law for a homogeneous superconductor, to a model of similar form, valid on a larger space scale. The process, which can be iterated to higher and higher space scales, consists in solving for the fields e and j over a "periodicity cell" with periodic boundary conditions.<>Show More

A dual scheme is proposed, that correctly represents the electromagnetic fields as differential forms.
