Plasma influence on the dispersion properties of finite-length, corrugated waveguides
(The American Physical Society, 1996-03)
We present an experimental study of the electromagnetic properties of transverse magnetic modes in a
corrugated-wall cavity filled with a radially inhomogeneous plasma. The shifts of the .resonant frequencies of
a ...
High power plasma filled backward wave oscillators
(SPIE, 1988-01)
Relativistic backward wave oscillators (BWOs) have proven to be relatively efficient,
high-power microwave sources in the centimeter wavelength range. Recent Soviet results
have indicated that the use of a background ...

Specific slow wave structures are needed in order
to produce coherent Cherenkov radiation in overmoded relativistic
generators. The electromagnetic characteristics of such
slow wave, resonant, finite length structures ...
Experimental high power plasma-filled backward wave oscillator results

We study the starting conditions for a large diameter
(diameter/wavelength = 4.8) finite length backward wave oscillator
designed for 24-GHz operation at the fundamental T M o l
mode. This geometry is very promising for ...

The electromagnetic fields of the higher order axial
resonant modes in a slow wave structure are analyzed and found
to have considerably different characteristics from those of the
conventional fundamental mode. Here, ...
Demonstration of efficiency enhancement on a high-power backward-wave oscillator by plasma injection
(American Physical Society, 1989)
An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power
relativistic backward-wave oscillator when plasma is injected is presented. Controlled plasma injection
enhances the ...
Observation of a resonant enhancement of microwave radiation from a gas-filled backward wave oscillator
(American Institute of Physics, 1988-08-15)
High-power microwave radiation at 8 GHz from a gas-fined backward wave oscillator driven
by an intense relativistic electron beam has been measured. It has been observed that an order
of magnitude resonant increase in ...
