Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

A multi-beam traveling wave amplifier designed with an overmoded staggered double
grating array was examined by small signal analysis combined with simulation. Eigenmode …

In this paper we suggest the new approach of powerful sub-THz signal generation based on
intense electron beams containing oscillating virtual cathode. Suggested compact …

Wakefield excitation has been experimentally studied in a three-cell X-band standing wave
photonic band gap (PBG) accelerating structure. Major monopole (TM 01-and TM 02-like) …

This paper presents an experimental comparative study of iron losses obtained by means of
the Epstein frame, Ring Core and dynamometer tests with non-oriented electrical steel …

The fabrication of two-dimensional terahertz photonic crystals using wet chemical etching of
high-resistivity silicon is described. Wet-etched photonic crystals with a sloped sidewall were …

Time-domain modeling of vacuum tubes is important for theoretical analysis of spurious
oscillation, amplification and generation of short pulses and complex multifrequency, or …

Various methods to generate ultrashort electron bunches for the ultrafast science evolved
from the simple configuration of two-plate vacuum diodes to advanced technologies such as …

This paper presents the design and fabrication of a reflex klystron oscillator based on a
carbon nanotube (CNT) cold-cathode. An X-band klystron oscillator structure is assembled …
