| Popis: |
The phase of the re∞ection coe-cient of a TE10 rectangular waveguide mode at the cut-ofi point in a gentle downtaper is investigated through both experiment and computer simulation. The result shows a very good agreement with the theoretical prediction based on the work by Katsenelenbaum etal., that is, a +90 - phase shift occurs at the cut-ofi point for TE modes if the cut-ofi point is not too close to the end of the downtaper. An application for the determination of the resonant frequencies for the spurious trapped TE30 mode in an uptaper-downtaper oversized resonant structure is presented. |
