Time-Domain Generalized Telegrapher's Equations for the Electromagnetic Field Coupling to Finite Length Wires Above a Lossy Ground

In this paper, a time-domain variant of the generalized telegrapher's equations for transient electromagnetic field coupling to a finite-length wire above a lossy half-space is derived. The approach is fully based on the thin-wire antenna theory. The lossy ...

Test Results of Three Poloidal Field Superconducting Samples in SULTAN

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

Superconductors for the ITER Poloidal Field Coils are large cable-in-conduit conductors (CICC) made of NbTi strands encased in a round-in-square stainless steel jacket. Three prototype conductor sections for poloidal field coils PF1/6, PF2/3/4 and PF5 have ...

Effect of Thermal Loading on Nb3Sn CICC Performance

Pierluigi Bruzzone, Boris Stepanov, Stephen Alfred March

The ITER CICC will undergo a number of cool-down and warm-up cycles over the lifetime of the plant. The standard SULTAN based ITER conductor qualification test normally includes one thermal cycle in the test sequence. In many samples a performance degradat ...

Comprehensive analysis of Lenz effect on the artificial heart valves during magnetic resonance imaging

Juan Ramon Mosig, Laleh Golestanirad

This work presents results of a comprehensive analysis of the Lenz effect due to motion of artificial heart valves during magnetic resonance imaging. The interaction of rotating metallic heart valves with magnetic fields is studied by performing a time-dom ...

Eigenvalues Analysis Applied to the Stability Study of a Variable Speed Pump Turbine Unit

Jean-Jacques Simond, Basile Kawkabani

This paper presents an eigenvalues analysis method for an induction machine model based on phase variables a, b, c. This approach is validated by comparison with ad, q approach and applied to a variable speed pump-turbine unit using a simplified model of t ...

Manipulation of giant Faraday rotation in graphene metasurfaces

Julien Perruisseau-Carrier

Faraday rotation is a fundamental magneto-optical phenomenon used in various optical control and magnetic field sensing techniques. Recently, it was shown that a giant Faraday rotation can be achieved in the low-THz regime by a single monoatomic graphene l ...

Review of design aspects for high current Nb3Sn conductors

Pierluigi Bruzzone

Cabled conductors based on Nb3Sn technology with operating current in the range of 20 kA and above are mainly restricted to fusion magnets and high field facilities. The experience of last decade has dramatically shown that, opposite to the NbTi conductors ...

Thermodynamics of electromechanically coupled mixed ionic-electronic conductors: Deformation potential, Vegard strains, and flexoelectric effect

Alexander Tagantsev

Strong coupling among external voltage, electrochemical potentials, concentrations of electronic and ionic species, and strains is a ubiquitous feature of solid statemixed ionic-electronic conductors (MIECs), the materials of choice in devices ranging from ...

THz-waves channeling in a monolithic saddle-coil for Dynamic Nuclear Polarization enhanced NMR

Stefano Alberti, Jean-Philippe Ansermet, Emile Jacques de Rijk, Alessandro Macor

A saddle coil manufactured by electric discharge machining (EDM) from a solid piece of copper has recently been realized at EPFL for Dynamic Nuclear Polarization enhanced Nuclear Magnetic Resonance experiments (DNP-NMR) at 9.4 T. The corresponding electrom ...
