He then focuses on microwave vacuum electronics, explaining the physics and theory of the interaction of electron beams with electromagnetic fields in quasi-stationary systems such as diodes and klystrons, systems with continuous interactions such as traveling wave tubes, backward magnetrons and crossed-field amplifiers, and systems based on stimulated radiation of classical electron oscillations.

The book consists of two parts: Part I focuses on the motion of charged particles in static fields, the theory of electron lenses, and the problems of formation and transport of intense electron beams are considered; Part II covers the principles and theory of the interaction of electron beams with electromagnetic waves in quasi-stationary systems (diodes, klystrons), systems with continuous interactions (traveling wave tubes and backward wave oscillators), crossed-field systems (traveling wave and backward wave tubes of M-type, magnetrons, crossed-field amplifiers.
