      This paper concerns propagation of surface waves along a plasma column, and their amplification by interaction with an electron beam penetrating the plasma. First, surface wave propagation is analyzed for stationary and drifting plasmas. In addition to undamped propagation, the dispersion relation describes infinite sets of modes which can be categorized as evanescent and One of the most methodical treatments of electromagnetic wave propagation, radiation, and scatteringincluding new applications and ideas Presented in two parts, this book takes an analytical approach on the subject and emphasizes new ideas and applications used today. Part one covers fundamentals of electromagnetic wave propagation, radiation, and scattering. It provides ample end-of +Wave.

      This book addresses the peculiarities of nonlinear wave propagation in waveguides and explains how the stratification depends on the waveguide and confinement. An example of this is an optical fibre that does not allow light to pass through a density :// An RF probe is used to study the slow waves launched by phased waveguides in the frequency range from lower hybrid to electron plasma frequencies. It is shown that slow waves can penetrate an overdense plasma column only if the magnetic field exceeds a critical value consistent with the (modified) accessibility criterion. This criterion has formed the basis for the design of lower-hybrid slow M/abstract.

    The Maxwell wave Equations have been numerically solved for the case of a cylindrical plasma-filed waveguide with perfectly conductive walls. The calculations have been done using the SPIREs code, which solves the electromagnetic propagation in frequency domain along the radius of the waveguide by means of a mixed spatial-spectral method (1D-space along radius, spectral domain along azimuthal Results of a numerical analysis of the natural modes of multilayer plasma-dielectric waveguides are presented. The characteristics of fast and slow waves in open and shielded waveguides are :// B/abstract.

It is shown that the space charge wave modes of propagation which are usually associated with the drifting motion of an electron beam can also propagate and carry energy in stationary electron beams or plasmas of finite transverse cross section. The properties of these modes of propagation have been studied by considering the plasma as a dielectric and solving the field :// Additional Physical Format: Online version: Trivelpiece, Alvin W., Slow-wave propagation in plasma waveguides.

Unlike previous calculations, a nonzero collision frequency is retained throughout.

An example of this is an optical fibre that does not allow light to pass through a density :// The paper considers the propagation behaviour of a circular waveguide enclosing either an axial or an annular column of isotropic plasma.

The effect of the glass walls of the container required to enclose an actual gaseous plasma is exactly taken into account. The phase-change and attenuation coefficients of both structures are computed for a range of parameters relevant in microwave :// Abstract.

The phenomenon of electromagnetic surface wave propagation along the interface between a preexisting plasma column and its surrounding dielectrics has been recognized and described in detail decades ago.

1?2 Later, in the early seventies, these waves began to be used to sustain plasma columns. 3,4 These so-called surface-wave discharges (SWD) exhibit many advantageous features: Abstract. The studies on the non-linear behaviour of surface waves (SWs) started many years ago with the pioneering works by Alanakyan 1 and Boev and Prokopov 2 where the non-linear dispersion relations (NLDRs) of the waves in the whole region of their propagation (electrodynamical study) in semi-bounded plasmas are derived at striction 3,4 and ionization ://   This paper studies the possibility of using a laser‐generated ‘‘plasma waveguide’’ to transfer electromagnetic (EM) energy.
