A sketch of the frequency measurement setup for a PEFP low-beta dumbbell.
A sketch of the perturbation measurement setup for a PEFP low-beta dumbbell.
TM010 mode field distributions of a left half cell, a right half cell; and the TM010 and mode field distributions of a dumbbell combined by these two half-cells simulated by CST MICROWAVE STUDIO.
TM010 mode field distributions of a dumbbell for different tip positions simulated by CST MICROWAVE STUDIO.
The sketches to tune the individual half cells and the PEFP tuning set. (a) Stretch a half cell and increase its TM010 mode frequency; (b) press a half cell and decrease its TM010 mode frequency.
The setup to measure the PEFP dumbbell frequencies.
A simulated dumbbell based on the PEFP low-beta middle half cells.
The individual half-cell frequencies of a PEFP low-beta dumbbell before a tuning and after a tuning, and the trimming length at the equators of a tuned dumbbell.
