Is shown that in the nonmagnetized plasma, besides longitudinal Langmuir resonance can exist the transverse plasma resonance. The resonance indicated can exist in the confined plasma. It is known that with the nuclear explosions the electromagnetic radiation in the very wide frequency band is observed, up to the radio-frequency range. And if the emission in field of light range can be explained by the emission of separate atoms, then emission in the region of radio-frequency band can be caused only by collective processes, which occur in the confined plasma. The use of transverse resonance makes it possible to create resonators and band-pass filters, and also lasers on the collective plasma oscillations. Transverse plasma resonance can be used also for the warming-up of plasma and its diagnostics. Is introduced the concept of magnetoelectrokinetic waves.

A New Tipe of Contact Potential Difference and Electrification of Superconducting Coils and Tori

by F. F. Mende

Original Research

The contact potential difference this is the potential difference, which appears between the located in the electrical contact conductors under the thermodynamic equilibrium conditions. As a result this between the conductors occurs the electron transfer until the Fermi levels in both conductors are made even. The established contact potential difference is equal to difference the work function of conductors, referred to the electron charge. In the article is described the new type of contact potential difference, which appears with the flow of the current through conductors. Contact the potential difference indicated depends on the strength of current, which flows through conductor; therefore it it is possible to name aelektrocurent contact potential difference. The results of investigating the electrification of the superconductive windings and tori during the introduction in them of direct currents are represented. Are proposed the schematics of magnetometers, which make it possible to measure the magnetic fields over a wide range of their values.

New Properties of Reactive Elements and the Problem of Propagation of Electrical Signals in Long Lines

by F.F. Mende

Original Research

Are examined the laws of the self-induction of capacitance and inductance, which it is customary to assume as reactive elements. It is shown that with the connection to the sources of direct current and voltage they have the effective resistance, which depends on the time. Is examined the parametric self-induction of the elements indicated and it is shown that in the regime of parametric self-induction the capacitance and inductance can not only derive energy from the power sources, but also return it into the external circuits. The velocity of propagation of constant voltages and currents in the long lines is obtained. In this case the laws of parametric self-induction are used. This task cannot be solved, using standard wave equations for the long lines.
