We study the dependence of the absorption coefficient on the electric and magnetic fields, and direction of the applied electric field. It turns out that the transverse magnetic and electric fields produce notable changes in the optical properties of quantum wire. Numerical results are presented ...
5.3 FERROMAGNETIC MATERIALS Some materials modify applied magnetic fields by alignment of bound atomic currents. Depending on the arrangement of electrons, atoms may have a magnetic moment. This means that the circulating electrons produce magnetic fields outside the atom. The fields, illustrated in ...

In addition, the presence of magnetic fields produce an enhancement at the light shinning through wall experiments designed in [28, 29], which may be seen in a near future. Further applications of these non linearities for laser fields were considered in [40]. In addition, the interaction ...
A calculation of the electric and magnetic fields at the Earths surface due to an ionospheric electrojet system is required for the estimation of geomagnetically induced currents (GIC) in a technological network, which are a manifestation of space weather effects on the ground. Two models of the...
studies on lambs, baboons and humans do not support such an effect of electromagnetic fields, while in vitro studies have shown that exposure to electromagnetic fields at usual residential levels (<100 μT) does not produce any significant in vitro effects that could be replicated in independen...
An external electric or magnetic field can transfer high-intensity energy directly to the electronic scale of materials, and change the spin, energy level arrangement and trajectory of electrons. These changes produce tremendous and profound impacts on t
The EMF travels through space in the form of electromagnetic waves (radiation), which consist of two coupled elements: magnetic and electric fields. The speed of the electromagnetic wave depends on the electric and magnetic permittivity of the environment; for an instant, in a vacuum, it travels...
4.1 Plasma in electric and magnetic field In this section we will consider charged particle behavior in electric and magnetic fields using a single particle approach. One peculiarity of this approach is that both electric and magnetic fields will be considered given and independent of the plasma pro...
The full vector nature of these measurements has provided the most complete set of wave and DC magnetic field measurements ever made in the Earth’s inner magnetosphere. Of particularly note is the full 3D nature of the WFR measurements of both electric and magnetic fields. The 3D nature of ...
