Abstract

Microwave and plasma interaction is examined via two fundamental TE{sub 10} modes propagating in a plasma filled rectangular waveguide after superposing at a smaller angle. The propagation of the resultant mode realized from these two modes is governed by a wave equation obtained using the Maxwell's equations. This equation is solved numerically using fourth order Runge-Kutta method for the field amplitude of the microwave in the waveguide considering the waveguide to be made up of a perfect conductor and filled with different types of initial plasma density distributions, viz. homogeneous density, linear density with gradient in the propagation direction, and the density with Gaussian profile along the waveguide width. A phenomenon similar to the duct formation by high power microwaves is found to take place, where the plasma density attains interesting profiles. These profiles can be controlled by the angle of superposition, phase difference between the fields of the two modes, microwave frequency and microwave field amplitude.

Microwave and plasma interaction in a rectangular waveguide: Effect of ponderomotive force

Journal Article Malik, Hitendra; Aria, Anil - Journal of Applied Physics

Studies on the propagation of high power microwave and its interaction with a plasma in a metallic waveguide are carried out. For this we consider the fundamental TE{sub 10} mode that propagates in an evacuated rectangular waveguide and encounters a plasma which is filled in another waveguide of the same size. Using Maxwell's equations we evaluate the field components of the mode in the evacuated waveguide and then obtain coupled differential equations for the field components of the mode in the plasma filled waveguide, where the plasma effect enters in terms of its dielectric constant. These equations are solved numericallymore »« less

Influence of ponderomotive force on the microwave and plasma interaction in an elliptical waveguide

Journal Article

The interaction effect of a high-power microwave with the plasma in an elliptical waveguide taking into account the ponderomotive force is presented. Here, we assume the fundamental mode that propagates in an evacuated elliptical waveguide and encounters a plasma, which is filled in another elliptical waveguide of the same size. Here, we consider a balance between the effects of ponderomotive force and the electron pressure and consider the plasma effect through its dielectric permittivity because the electron density distribution of the plasma is modified. The propagation of the mode is described by two nonlinear coupled differential equations obtained using themore »« less

Electron dynamics and acceleration study in a magnetized plasma-filled cylindrical waveguide

Journal Article Kumar, Sandeep; Yoon, Moohyun - Journal of Applied Physics

In this article, EH{sub 01} field components are evaluated in a cylindrical waveguide filled with plasma in the presence of external static magnetic field applied along the direction of the mode propagation. The electron acceleration inside the plasma-filled cylindrical waveguide is investigated numerically for a single-electron model. It is found that the electron acceleration is very sensitive to the initial phase of mode-field components, external static magnetic field, plasma density, point of injection of the electron, and microwave power density. The maximum amplitude of the EH{sub 01} mode's field components is approximately 100 times greater than the vacuum-waveguide case formore »« less

Two-dimensional calculation of short electromagnetic pulse propagation and ionization in low-pressure, argon-filled cylindrical cavities

Conference Mayhall, D; Yee, J

Two-dimensional, electromagnetic, finite difference, electron fluid computer codes have previously been used to calculate short-pulse (1--20 ns), high-power (1--70 MW) microwave breakdown and transmission effects in low-pressure (1--600 torr), air-filled, rectangular and parallel plate waveguides. The relevant Maxwell curl equations were solved self-consistently with the first three moments of the Boltzmann equation under the assumption of a Maxwellian velocity distribution. Since the primary focus of the work was on the transmitted electromagnetic wave, instead of the details of the plasma generated by the incident wave, approximate electron fluid equations wee employed. In the present investigation, the authors made the fluidmore »« less
Intense microwave pulse propagation through gas breakdown plasmas in a waveguide

Thesis/Dissertation Byrne, D

High-power microwave pulse-compression techniques are used to generate 2.856 GHz pulses which are propagated in a TE/sub 10/ mode through a gas filled test section of waveguide, where the pulses interact with self-generated gas-breakdown plasmas. Pulse envelopes transmitted through the plasmas, with durations varying from 2 ns to greater than 1 ..mu..s, and peak powers of a few kW to nearly 100 MW, are measured as a function of incident pulse power and gas pressure for air, nitrogen, and helium. In addition, the spatial and temporal development of the optical radiation emitted by the breakdown plasmas are measured. For transmittedmore »« less
