output waveguideThe excitation of very high-order modes in circular waveguides has been performed in a cavity with a connected up-taper with a geometry similar to those used in gyrotrons. A Gaussian beam was coupled to the cavity which was made translucent by an array of holes. With the ...
VARIOUS authors have discussed hybrid modes in circular iris-loaded waveguides, from the points of view of pulse shortening, or beam blow-up, in high-current electron linear accelerators 1–5 and of high-energy particle separators 5–7 . Pulse shortening has been shown to be caused by ...

circular evanescent waveguidesegmentscoaxial lineThe eigenfrequencies of magnetic modes in a resonator made up of two segments of a circular evanescent waveguide and a coaxial line are found by solving an electrodynamic problem. For the fundamental H 11delta mode, the performance of the resonator is...

Based on what you just said, I think you would benefit from studying the details of the "Lossy circular waveguide" example provided by Comsol in the Comsol Application Library, which can be found in the "Transmission Lines and Waveguides" section of the "RF Module" part of the library. Goo...
may already see a difficulty: If the frequency is so high that there are many possible modes, you would have to add aPortboundary condition for each one. This is not a big problem for this 2D rectangular waveguide with only two modes supported, but suppose you have a3D circular waveguide?
This waveguide theory and the waveguide equations are true for any waveguide regardless of whether they are rectangular or circular.It can be seen that the different waveguide modes propagate along the waveguide in different ways. As a result it is important to understand what he available ...
The E^ and Efj modes are easily obtained by the conversion from HEn mode in the circular corrugated waveguide with efficiency of 99.3% [9]. For the alternative ITER antenna for electron cy- clotron heating with remote steering, the length of antenna is required to be 8a2/Xo (or 4a2/A0...
