Abstruct-A dielectric coated hemispherical conductor mounted on an infinite perfectly conducting ground plane and fed by a coaxial transmission line is investigated. Green's functions for the region above the ground plane are derived with separated homogeneous and particular solution parts so as to be compatible with numerical analysis techniques. A magnetic field integral equation is construct...

The influence of an external electric field on the spin dynamics of an electrically neutral Fermi liquid is considered, the mechanism of such an influence being the relativistic spin-orbital interaction. As a result, Leggett’s equations for the spin dynamics of weakly polarized Fermi liquids are generalized to the case of non-zero external electric field. In addition, we obtained the transverse...

Electron beams narrowly collimated to the magnetic field line were observed continuously from a downward current region to an auroral acceleration region (i.e., upward current region). They were well correlated with lowfrequency electric field fluctuations in the auroral acceleration region as well as in the adjacent downward current region. Magnetic field fluctuations were found only in the do...

In this article are presented the basic principles of the numerical protections used for protecting the high-voltage electric lines (110 kV). Is achieved a study for implementing a numerical distance protection DIPA 100, for a high-voltage line (an example from practice). For the numerical relay, is shown the protection characteristic of DIPA 100, characteristics of operation to faults ‘phase-p...

The embedded meander line in stepped-impedance resonator (SIR) is proposed to design narrow bandpass filter with a good stopband characteristics. The design differs from the general SIR configuration in that the microstrip lines are bent at the location of the maximum magnetic field density. As a result, the resonators have high external quality factors by themselves, since the factor is closel...

Considering the effects of the electric field on the low temperature absorption line of quantum well excitons, we show that, for moderate strength of the electric field, the main contribution to the field dependence of the linewidth results from the field induced modifications of the inhomogeneous broadening of excitons. We find that the strength of the random potential acting on the quantum we...

Automobile emissions such as carbon dioxide, nitrogen oxide and particulate matter are coming under progressively strict regulations worldwide. Meeting the increasingly severe requirements will require wider use of electric vehicles, including hybrid electric cars, and of high-efficiency electrified powertrains for better fuel economy. For this, implementation of still more compact, higher outp...
