Rectangular waveguide characterization for reflectometry

IEEE Transactions on Instrumentation and Measurement, 1988
Simple first-order correction formulas are developed to describe the combined effect of wall distortion and wall loss on the propagation constant and normalized impedance of nominally rectangular waveguides intended for use in reflectometry. A simple method of measuring the propagation constant at a single frequency is described, resulting in practical

Modes of crossed rectangular waveguide

IEEE Transactions on Antennas and Propagation, 1976
The cutoff frequencies and modal fields of dually polarized crossed rectangular waveguide are calculated numerically and the cutoff frequencies verified experimentally. Symmetry arguments and group theory are used to explain mode degeneracies and mode splitting. The single mode bandwidth is 38 percent of center frequency for both polarizations when the

Bends in oversized rectangular waveguide

Fusion Engineering and Design, 2011
Abstract The use of rectangular oversized waveguides in the Main Transmission Lines of the Lower Hybrid Current Drive (LHCD) system of ITER, requires to investigate the problem of bends. The principal specifications that characterize the oversized bend design concern the minimization of the reflection of the fundamental mode and the maximization of ...

Propagation in the General, Rectangular Waveguide

1975 5th European Microwave Conference, 1975
Two methods for calculating the propagation characteristics of rectangular waveguides with various internal and external media are presented. The first one is only asymptotically correct and utilizes the reflection coefficients from the walls, taking into to account depolarization. Results are presented for dielectric waveguides and rectangular tunnels

Conducting Spheres in Rectangular Waveguides

IEEE Transactions on Microwave Theory and Techniques, 1980
A conducting sphere on the center of the broad wall of a rectangular waveguide causes frequency independent reflections for a wide range of frequencies. This empirically found behavior is confirmed analytically here by perturbational calculations.

Propagation and impedance in rectangular waveguides

2000
The description of any waveguide includes its cut-off number, its propagation constant, one or more definitions of impedance, power flow and attenuation and a description of its field pattern. Since the rectangular wave guide embodies all the salient properties of the ridge waveguide it is apt to review some of its more important features before ...
