Abstract

An embodiment of the present invention provides a dynamically tuned waveguide and microwave plasma device, including a waveguide cavity and an adjustment device, and the adjustment device is movably connected to the waveguide cavity, and the adjustment changes when adjusting the adjustment device. The field type of the waveguide cavity. By changing the distance that the adjustment device enters the waveguide cavity, the microwave field pattern and reflection coefficient of the microwave of a specific frequency can be dynamically changed when it is transmitted in the waveguide cavity, and the best microwave coupling and transmission efficiency can be obtained, so that the microwave of a specific frequency can pass through the waveguide cavity The emission loss during in vivo transmission is the smallest, and at the same time, the waveguide provided by the embodiment of the present invention can be applied to various occasions that need to adjust electromagnetic wave coupling and impedance matching, and has a simple structure and is easy to implement.

Description

technical field [0001] Embodiments of the present invention relate to the field of microwave technology, and more specifically, to a dynamically tuned waveguide and microwave plasma device. Background technique [0002] The high-power microwave plasma device is a high-efficiency electrodeless lamp, which can generate high-brightness light with a wide spectrum in infrared, visible light and ultraviolet light. It is used for lighting, strong irradiation and material curing. It has no filament, no electrode, Strong luminous efficiency, low energy consumption, long service life and other technical advantages, the luminous flux can be almost constant, and the super-brightness with basically no attenuation throughout the life span. [0003] The high-power microwave plasma device contains a quartz ball with a diameter of about 30mm. The ball contains argon and other filling substances to generate light of different wavelengths. The bulb is placed in a metal mesh microwave cavity. ...
