This article reviews the state-of-the-art in high-power microwave source research. It begins
with a discussion of the concepts involved in coherent microwave generation. The main …

Volume 2 of the book begins with chapter 6, in which we have taken up conventional MWTs
(such as TWTs, klystrons, including multi-cavity and multi-beam klystrons, klystron variants …

This article presents a historical review of key ideas and main milestones of the research
and development of microwave generators with a virtual cathode in the Russian Federal …

This article presents the concept of multivircators, in which a chain of virtual cathodes (VCs)
is formed in two counter-streaming electron beams (exceeding the space charge limit) that …

Physics of Intense Beams in Plasmas is a comprehensive description of the interaction
between extremely intense particle beams and plasmas. The emphasis is on experimental …

Particle-in-cell (PIC) simulation of a two-foil magnetoinsulated vircator is carried out.
Evolution of electron phase portrait has been studied. Formation of two regions with a …

We presented a vircator with conical ballistic focusing and carried out the PIC simulation of
the dynamics of electrons in it. It is shown that the virtual cathode has the shape of a …

A relativistic magneto-isolated vircator on the underlimit electron beam is studied. It
contained two serial magnetic mirrors and a coaxial output of microwave radiation. Its 2.5-D …

A gas-discharge magnetically insulated vircator containing two tubes, one of which is filled
with low-pressure gas is proposed. Its particle-in-cell (PIC)/Monte Carlo (MC) simulation is …

A method is proposed for producing microwave generation in a relativistic magnetically
insulated vircator in the under-limit mode of an electron beam. The method is implemented if …
