Scattering at Rectangular-to-Rectangular Waveguide Junctions

IEEE Transactions on Microwave Theory and Techniques, 1982
A formally exact solution is given for the problem of scattering at a circular-to-rectangular waveguide junction and at a thick diaphragm, with a centered circular aperture, in a rectangular waveguide. The method uses normal TE and TM mode expansions of the waveguide fields and traditional mode matching of the transverse electric and magnetic fields at

Characteristics comparison of substrate-integrated rectangular waveguide (SIRW) and its equivalent rectangular waveguide

Microwave and Optical Technology Letters, 2005
The propagation and loss characteristics of the substrate-integrated rectangular waveguide (SIRW) at microwave and millimeter-wave bands are investigated. The results further verify that the substrate-integrated rectangular waveguide has nearly the same waveguide characteristics as conventional rectangular waveguides, and it can be analyzed as a ...

Multipactor in rectangular waveguides

Physics of Plasmas, 2007
Multipactor inside a rectangular waveguide is studied using both an analytical approach and numerical simulations. Particular attention is given to an analysis of the role of such effects as the velocity spread of secondary emitted electrons and the action of the rf magnetic field on the electron motion.
