Relativistic effects on the TM-modes of one boundary corrugated parallel plate waveguide filled with uniaxial warm drifting plasma
نویسندگان
چکیده
The relativistic effects on the TM-modes of one boundary corrugated parallel plate waveguide filled with uniaxial warm drifting plasma have been investigated. The dispersion relation for the TM-modes has been derived and the numerical computations have been carried out to study the effects of increased (relativistic) drift velocity and the temperature under this condition. The effects of drift velocity are quite distinct and significant over the non-relativistic case. The effect of temperature in the relativistic case is remarkably insignificant unlike the nonrelativistic case where it was quite pronounced. J. Phys.

Linear analysis of a finite length plasma-filled backward wave oscillator
Absolute instability in a plasma-filled backward wave oscillator with sinusoidally corrugated slow wave structure driven by an intense relativistic electron beam has been analyzed numerically. The maximum spatial growth rate of the plasma-filled waveguide is found to be larger than that of an optimally designed vacuum structure. The excitation of a finite length structure is investigated. Altho...
متن کاملDyadic Green’s Functions for a Parallel Plate Waveguide Filled with Anisotropic Uniaxial Media
The dyadic Green’s functions for magnetic and electric currents immersed in a parallel plate waveguide (PPWG) filled with dielectric-magnetic anisotropic uniaxial media are developed via a field-based approach. First, the principal Green’s function is derived from the forced wave equation for currents immersed in an unbounded uniaxial media. Next, the scattered Green’s function is developed fro...

متن کاملIty of Modes in a Parallel Plate, Anisotropic Waveguide Using a Modified, Coordinate Transformation
The excitation of forward and backward, Electromagnetic (EM) modes and fields in an anisotropic, parallel plate waveguide (meeting Dirichlet and Neumann boundary conditions), is studied, using a modified coordinate transformation which reduces Maxwell’s equations to the form of a Helmholtz wave equation satisfying Dirichlet and mixed-partial derivative boundary conditions. The EM modes and fiel...
متن کاملPropagation of Single-Mode and Multi-Mode Terahertz Radiation Through a Parallel-Plate Waveguide
We investigated the propagation of singleand multi-mode terahertz (THz) radiation through a parallel-plate waveguide for various gap sizes of the plates and polarizations of the incoming THz eld. Single TEM (TM0) and TE1 modes within the 4-THz frequency range propagated through a waveguide with a plate separation of 103 m. Multi TE and TM modes were observed for a 360m separation. High-order mo...
