We present a comprehensive model of the global properties of Alfvén waves in the solar atmosphere and the fast solar wind. Linear non-WKB wave transport equations are solved from the photosphere to a distance past the orbit of the Earth, and for wave periods ranging from 3 s to 3 days. We derive a radially varying power spectrum of kinetic and magnetic energy fluctuations for waves propagating ...

The effective large-scale Hamiltonian of a planar system of nano-loops in a weakly excited flux-closed magnetized state has been constructed by means of a perturbative technique based on micromagnetic theory. The Hamiltonian is written by means of two classes of collective variables: the continuous soft spins and discrete vorticity charges. Analytical and numerical calculations of the inter-loo...

Spin waves are promising chargeless information carriers for the future, energetically efficient beyond CMOS systems. Among many advantages ease of achieving nonlinearity, variety possible interactions, and excitation types. Although rapidly developing magnonic research has already yielded impressive realizations, multimode nonlinear effects, particularly with propagating their nanoscale still ...

Abstmcr. The Cassini spaceaaft , launched in October 1997 to reach Saturn in 2004, carries two magnetometer xperiments on a lo-meter boo”, one at the mid-section of the boom and the other at the end of the boom. In order to gather valid scientific magnetic field data and avoid electromagnetic nterference, the spacecraft had to comply with stringent magnetostatic cleanliness requirements. Amidst...

The paper presents the solution of a three-dimensional (3-D) magnetostatic problem using the finite formulation of an electromagnetic field. Two different approaches, based on a primal-dual barycentric discretization of the 3-D space, are presented, considering as unknowns either the magnetic fluxes or the circulations of the vector potential. Results on simple reference configurations are repo...
