We examine specific features of the realisation of the beam pulse amplifier (BPA) mechanism of chorus excitation in the density ducts that have a width of the order of 100–300 km with refractive reflection. The dispersion characteristics of whist

Abstract The effect of weak external influences associated with infrasonic waves in the ionosphere on the operation of a plasma magnetospheric maser (PMM) is considered. It is shown that if the frequency of infrasonic waves is close to the eigen freq

A model for the source of microwave main giant pulses (GPs) from the Crab pulsar is proposed and partly investigated. Pulse excitation takes place in a relativistic pair plasma with a strong magnetic field through the beam pulse amplifier (BPA) mecha

The preconditions for the formation of electron temperature jumps with scales comparable to the mean free path of electrons in the solar atmosphere are examined. In regions with heat flux, noise electric fields can arise due to ion-acoustic plasma tu

By combining the analytical approach and the test particle simulation, we examine the possibility of strong amplification of appropriate weak electromagnetic pulse in a magnetized plasma layer. Amplification occurs with the rate of instability of the

Some aspects of the theory of generation of magnetospheric chorus are discussed. An original approach to solving the problem of oblique chorus generation near the Gendrin angle is outlined and partially realized within the framework of a beam pulsed

Trans-ionospheric propagation of the VLF electromagnetic wave from an altitude of 800 km to the Earth's surface is considered using the model of stratified media. The numerical solution of the wave equations for the mid-latitude ionosphere model cond
