| Abstract: | Competition of the operating modes at the second cyclotron harmonic with spurious modes at fundamental is studied numerically for the cases of gyrotron and traveling opposite spurious modes in the gyrotron FU II. This competition limits significantly the output power at the second harmonic. The results are in good agreement with experiments. |
| Keywords: | gyrotron fundamental and second cyclotron harmonics mode interaction opposite wave |
