Abstract (en)
A microwave resonant cavity (10) includes a conductive shell (20) with a screw hole (21) having first threads (23) and a screw (30) having second threads (33) configured to engage with the screw hole. The conductive shell defines a volume, the screw extends into the volume, the microwave resonant cavity has a resonant frequency, and the movement of the screw changes the resonant frequency. The first threads have a first pitch, and at least a portion of the second threads has a second pitch different from the first pitch.
