Investigation of intertype oscillations in the barrel-shaped open resonator

The results of experimental investigation and theoretical analysis of interaction processes of different type of oscillations in the Barrel-Shaped Open Resonators (BORs) are presented. All experiments were made in four-millimeter wave range. We used mechanically retunable BOR designing with a longitudinally narrow slot. In result a frequency ranges for interacting modes TEM and TE were defined and a behavior of Q-factor of modes was studied in range of interaction.
