Waveguides: characteristic modes of hollow rectangular dielectric waveguides

Applied Optics, 1976
The field configurations and propagation constants of the normal modes of a hollow rectangular dielectric waveguide have been determined. In addition, the coupling coefficients of a Gaussian free-space mode into the normal modes of a square guide were calculated.

Open resonators powered by a rectangular waveguide

IEE Proceedings H Microwaves, Antennas and Propagation, 1992
In the paper, by taking into account both diffraction and ohmic losses, a complete analysis of the excitation of an open resonator is developed. The coupling between the rectangular feeding waveguide and the cavity is fully considered, by taking into account all the relevant modes in the waveguide and the open cavity, in order to derive the coupling ...

Rectangular Dielectric Waveguides

2003
The rectangular dielectric waveguide is the most commonly used structure in integrated optics, especially in semiconductor diode lasers. Demands for new applications such as high-speed data backplanes in integrated electronics, waveguide filters, optical multiplexors, and optical switches are driving technology toward better materials and processing ...

Properties of Rectangular Waveguides

1971
For considerations about the propagation of the TM and TE waves derived in Chapter 13 the common factor exp [jωt-Гz] suffices here. The precise form of the electromagnetic field in a given cross-section where z = constant is not relevant in this connection.

The miniaturization of rectangular waveguide

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
This paper presented a miniaturization rectangular waveguide which much smaller than hallow rectangular waveguide (HRWG) having same cutoff frequency of dominant mode and a large bandwidth of single dominant mode working (BWSMW) by inserting a suspended dielectric layer which partly covered a metal grounded plane.

Piecewise-uniform bends in rectangular waveguide

IEEE Microwave and Wireless Components Letters, 2005
A new configuration of improved rectangular-waveguide bend for advanced millimeter-wave applications is presented. It consists of few lengths of constant-curvature bends, properly designed in order to obtain enhanced matching conditions, without matching elements.

Development of Coplanar Waveguide to Rectangular Waveguide Transition

2009 Annual IEEE India Conference, 2009
This paper deals with a transition between CPW and rectangular waveguide suitable in phased array antenna environment. In case of phased array antenna where the scan angles are very large, the sub array size gets reduced. Hence in such cases the feed element size becomes very small and the accommodation of active module comprising phase shifter and ...

Rectangular waveguide impedance

13th International Crimean Conference Microwave and Telecommunication Technology, 2003. CriMiCo 2003., 2003
Presented in this paper is the analytical dependence of H/sub 10/ wave impedance on parameters b/a and a//spl lambda/ for the waveguide with cross-section a/spl times/b. For the given value a//spl lambda/, the function Zg(b/a) can be approximated by function A(b/a)Zc/sub 10/(b/a), where constant A possesses values from 0,5 up to 2 over the waveguide ...
