Abstract. The calculation of a mode filter for a circular waveguide designed to isolate a high-order TE mode consistent with its field has been carried out. A theoretical justification and results of electrodynamic modeling are given using the example of identifying the third harmonic TE12,4 mode of the gyrotron against the background of predominant radiation at the fundamental cyclotron harmonic in the TE4,2 mode.

Key words: gyrotron, millimeter waves, waveguide filter.

Financing: The work was supported by the Russian Science Foundation, project №23-12-00161.
