| 发明名称 | Microwave resonant cavity | ||
| 摘要 | A microwave resonant cavity includes a conductive shell with a screw hole having first threads and a screw having second threads 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. | ||

| 主权项 | 1. A microwave resonant cavity, comprising: a conductive shell defining a volume, and the conductive shell including a screw hole having first threads; and a screw having second threads configured to engage with the screw hole, wherein the screw extends into the volume, wherein the microwave resonant cavity has a resonant frequency, and movement of the screw changes the resonant frequency; wherein 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, and wherein the screw has a front portion having third threads and a back portion having the second threads, and the third threads have a third pitch different from the second pitch. | ||
