Generalized Electric Field Equations of a Time-Varying Current Distribution Based on the Electromagnetic Fields of Moving and Accelerating Charges

In several studies conducted recently, it was shown that equations pertinent to the electric and magnetic fields produced by electrical charges in motion can be used to calculate the electromagnetic fields produced by current pulses propagating along linea ...

The 16 T Dipole Development Program for FCC and HE-LHC

Pierluigi Bruzzone, Stephan Russenschuck, Peng Gao, Luca Bottura, Mariusz Juchno, Bernhard Auchmann, Giuseppe Montenero

A future circular collider (FCC) with a center-of-mass energy of 100 TeV and a circumference of around 100 km, or an energy upgrade of the LHC (HE-LHC) to 27 TeV require bending magnets providing 16 Tin a SO-mm aperture. Several development programs for th ...

Colossal mid-infrared bulk photovoltaic effect in a type-I Weyl semimetal

Philip Johannes Walter Moll, Xiangwei Huang, Xu Yang

Broadband, efficient and fast conversion of light to electricity is crucial for sensing and clean energy. The bulk photovoltaic effect (BPVE) is a second-order nonlinear optical effect that intrinsically converts light into electrical current. Here, we dem ...

Electrical integration of two 1MW/2s dual-frequency gyrotrons into the EC-system of the TCV tokamak

Stefano Alberti, Damien Fasel, Ugo Siravo, Jérémie Dubray, Albert Perez

The electron-cyclotron heating system of the TCV tokamak is being enhanced as part of a major upgrade. Two MW-class dual-frequency gyrotrons will be installed. The first has already been delivered and will be fully commissioned on-site by the end of 2018 w ...

Persistent antiferromagnetic order in heavily overdoped Ca1-xLaxFeAs2

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Philip Johannes Walter Moll, Ana Akrap, Sergiy Katrych, Maja Deborah Bachmann, Edoardo Martino

In the Ca1-xLaxFeAs2 (1 1 2) family of pnictide superconductors, we have investigated a highly overdoped composition (x = 0.56), prepared by a high-pressure, high-temperature synthesis. Magnetic measurements show an antiferromagnetic transition at T-N = 12 ...

Electrical transport in onion-like carbon-PMMA nanocomposites

László Forró, Arnaud Magrez, Claudio Grimaldi, Maryam Majidian

We report electrical conductivity measurements of polymethyl-methacrylate filled by onion-like carbon particles with a primary particle size of approximate to 5 nm. We show that the conductivity sigma is exceptionally high even at very low loadings and tha ...

Frequency Response of Electric and Magnetic Fields of Overhead Conductors With Particular Reference to Axial Electric Field

Complete electric and magnetic field solutions of an overhead conductor above a lossy earth are derived in this letter, and “mode transition” from a low-frequency quasi-transverse electromagnetic (TEM) to a high-frequency transverse Magnetic (TM) mode has ...

Modeling of EMP Coupling to Lossless MTLs in Time Domain Based on Analytical Gauss-Seidel Iteration Technique

Jun Guo

This paper provides an efficient way to simulate the transient electromagnetic field coupling to overhead multi conductor transmission lines in time domain based on an analytical iterative technique. The method is entirely in time domain and therefore can ...

Transient Impedance of Interconnected Wind Turbine Grounding Systems

Marcos Rubinstein, Antonio Sunjerga, Qi Li

Wind turbines are very vulnerable to lightning because of their height, sharp edges and remote locations often with low soil conductivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We anal ...

A Semi-Analytical Method to Evaluate Lightning-Induced Overvoltages on Overhead Lines Using the Matrix Pencil Method

Jun Guo

Lightning electromagnetic fields can couple to overhead power transmission and distribution lines, causing serious effects to the power system. Lightning electromagnetic fields that couple to overhead lines have a nonuniform distribution along the line con ...
