The electron cyclotron maser (ECM) is based on a stimulated cyclotron emission process
involving energetic electrons in gyrational motion. It constitutes a cornerstone of relativistic …

The first edition of High Power Microwaves was considered to be the defining book for this
field. Not merely updated but completely revised and rewritten, the second edition continues …

As unique sources of coherent high-power, microwave, and millimeter-wave radiation,
gyrotrons are an essential part of the hunt for controlled fusion. Presently, gyrotrons are …

Reversed Cherenkov radiation is the exotic electromagnetic radiation that is emitted in the
opposite direction of moving charged particles in a left-handed material. Reversed …

We present the newly developed Maryland Gyrotron (MAGY) code for modeling of slow and
fast microwave sources. The code includes a time-dependent description of the …

Significant progress in modeling and manufacturing technologies open wide possibilities for
performance improvements of millimeter-wave vacuum electron devices. However, many …

A repetitive X-band relativistic backward-wave oscillator (BWO) driven by a SINUS-881
accelerator is described. Relativistic electron beams with peak current of 5.4 kA and voltage …

Basic wave-particle interaction dynamics from linear to chaotic regimes is experimentally
studied on a frequency tunable gyrotron generating THz radiation in continuous mode (200 …

We present an analysis of the beam dynamics in a Smith-Purcell free-electron laser (FEL). In
this system, an electron beam interacts resonantly with a copropagating surface …

Using the quasi-optical approach, we investigate wave propagation along the periodically
corrugated surfaces and their interaction with rectilinear relativistic electron beams (REBs) …
