Abstract

Embodiments of the present invention provide a dynamically tuned waveguide and a microwave plasma device. The dynamically tuned waveguide comprises a waveguide cavity and an adjustment device, the adjustment device is movably connected with the waveguide cavity, and the field pattern of the waveguide cavity is changed when the adjustment device is adjusted. By changing the distance that the adjustment device enters the inside of the waveguide cavity, the microwave field pattern and reflection coefficient of the microwave being transmitted at a specific frequency in the waveguide cavity can bedynamically changed, and the optimal microwave coupling and transmission efficiency is obtained, so that the transmission loss is minimal when the microwave at the specific frequency is transmitted inthe waveguide cavity. The waveguide provided by the embodiment of the invention can be applied to various occasions where the electromagnetic wave coupling and impedance matching need to be adjusted,and the structure is simple and the implementation is simple.
