Some recent advancements in the development of powerful high frequency gyrotrons that
generate coherent radiation in the sub-terahertz and terahertz regions of the …

Optoelectronic techniques for generation and detection of terahertz (THz) signals have been
reviewed. The operation principles of THz photomixer sources and THz parametric sources …

We experimentally demonstrate the production of narrow-band (⁠ δ f/f≈ 20% at f≈ 0. 5
THz⁠) transition radiation with tunable frequency over [0.37, 0.86] THz. The radiation is …

We report on the radiation studies performed at the CLEAR facility of CERN in the sub-THz
range, exploiting picosecond ultrarelativistic electron bunches for the production of coherent …

The study of modulated electron beams is important because they can be used to produce
coherent radiation, but the modulations can cause unwanted instabilities in some devices …

We propose a scheme for terahertz (THz) radiation generation by non-linear mixing of two
cosh-Gaussian laser beams in axially magnetized plasma with spatially periodic density …

We describe a new method to generate enhanced terahertz (THz) surface wave (SW) via its
coupling with reversed Cherenkov radiation (RCR), excited by a sheet beam bunch which …

We propose a type of hollow planar waveguide with corrugated walls, which can realize
electrically tunable terahertz (THz) filtering by filling the slit with liquid crystals. When the THz …

Thermionic electron guns are capable of operating at high average currents in a variety of
vacuum electronic applications, including conventional microwave tubes, but have been …

Two-dimensional electromagnetic particle-in-cell simulations were performed to study the
effect of the displacement current and the self-magnetic field on the space charge limited …
