moore s curve structuring of Ferromagnetic composite pe nife absorbers
Journal of Applied Physics, 2018Co-Authors: N Fernez, Patrick Queffelec, Younes Arbaoui, Azar Maalouf, Alexis Chevalier, P Agaciak, L Burgnies, Vincent Laur, E LheuretteAbstract:A Ferromagnetic Material involving nickel-iron particles embedded in a polyethylene matrix is synthesized and electrically characterized between 1 and 12 GHz. These measurements show the combination of electric and magnetic activity along with significant loss terms. We take benefit of these properties for the design of broadband electromagnetic absorbers. To this aim, we use a fractal structuring based on Moore curves. The advantage of etching patterns over metallic ones is clearly evidenced, and several pattern absorbers identified by their Moore's order iteration are designed and analyzed under oblique incidence.A Ferromagnetic Material involving nickel-iron particles embedded in a polyethylene matrix is synthesized and electrically characterized between 1 and 12 GHz.

magneto elastic stress subjected to uniform magnetic field over a thin infinite plate containing an elliptical hole with an edge crack
International Journal of Solids and Structures, 2011Co-Authors: Norio HasebeAbstract:Abstract Two dimensional solutions of the magnetic field and magneto elastic stress are presented for a magnetic Material of a thin infinite plate containing an elliptical hole with an edge crack subjected to uniform magnetic field. Using a rational mapping function, each solution is obtained as a closed form. The linear constitutive equation is used for these analyses. According to the electro-magneto theory, only Maxwell stress is caused as a body force in a plate. In the present paper, it raises a plane stress state for a thin plate, the deformation of the plate thickness and the shear deflection. Therefore the magneto elastic stress is analyzed using Maxwell stress. No further assumption of the plane stress state that the plate is thin is made for the stress analysis, though Maxwell stress components are expressed by nonlinear terms. The rigorous boundary condition expressed by Maxwell stress components is completely satisfied without any linear assumptions on the boundary. First, magnetic field and stress analyses for soft Ferromagnetic Material are carried out and then those analyses for paramagnetic and diamagnetic Materials are carried out. It is stated that those plane stress components are expressed by the same expressions for those Materials and the difference is only the magnitude of the permeability, though the magnetic fields H x , H y are different each other in the plates. If the analysis of magnetic field of paramagnetic Material is easier than that of soft Ferromagnetic Material, the stress analysis may be carried out using the magnetic field for paramagnetic Material to analyze the stress field, and the results may be applied for a soft Ferromagnetic Material. It is stated that the stress state for the magnetic field H x , H y is the same as the pure shear stress state. Solutions of the magneto elastic stress are nonlinear for the direction of uniform magnetic field. Stresses in the direction of the plate thickness and shear deflection are caused and the solutions are also obtained. Figures of the magnetic field and stress distribution are shown. Stress intensity factors are also derived and investigated for the crack length.

magnetic field and magneto elastic stress in an infinite plate containing an elliptical hole with an edge crack under uniform electric current
International Journal of Solids and Structures, 2010Co-Authors: Norio HasebeAbstract:Abstract Two-dimensional solutions of the electric current, magnetic field and magneto elastic stress are presented for a magnetic Material of a thin infinite plate containing an elliptical hole with an edge crack under uniform electric current.

If the analysis of magnetic field of paramagnetic Material is easier than that of soft Ferromagnetic Material, the stress analysis may be carried out using the magnetic field for paramagnetic Material to analyze the stress field, and the results may be applied for a soft Ferromagnetic Material. It is stated that the stress state for the magnetic field Hx, Hy is the same as the pure shear stress state. Solving the present magneto elastic stress problem, dislocation and rotation terms appear, which makes the present problem complicate. Solutions of the magneto elastic stress are nonlinear for the direction of electric current. Stresses in the direction of the plate thickness are caused and the solution is also obtained. Figures of the magnetic field and stress distribution are shown. Stress intensity factors are also derived and investigated for the crack length and the electric current direction.

correlation between magnetic properties of layered Ferromagnetic dielectric Material and tunable microwave device applications
Journal of Applied Physics, 2002Co-Authors: Erwan Salahun, Patrick Queffelec, G Tanne, A L Adenot, Olivier AcherAbstract:Layered dielectric / Ferromagnetic Materials are extensively explored for microwave applications. Indeed, these Materials combine the large saturation magnetization of Ferromagnetic Material with the low loss of dielectrics. Here, our aim was to integrate a layered Ferromagneticcomposite in a microwave propagation structure since the main advantage of such a Material is the large impedance for one polarization. Thus, in order to predict the transmission response of the device, we carried out an electromagnetic analysis to determine how the field pattern of a microstrip line and the microwave-induced demagnetizing fields disturb the Material behavior. We also explored the use of the propagation structure in two dc magnetic field-dependent devices: a tunable band stop filter and a magnetic switch. The stop-band function presented a large tunability of more than 50% with a minimal insertion loss of 3 dB when 250 Oe field was applied. Moreover, a magnetic switch using a dc field perpendicular to the easy axis of the Ferromagnetic Material was manufactured.
