Abstract

The invention discloses a high-power microwave output window which is coated with a diamond-like film on a periodic grooving surface and a manufacturing method thereof, which can be used for solving a problem that a surface high-power microwave breakdown threshold of the vacuum-side medium window surface cannot be effectively increased in the prior art. The method comprises the following steps: processing an organic polymer medium window surface into a waveform periodic surface structure; pre-processing the waveform periodic surface structure; in a vacuum furnace, performing vacuum-pumping to 1-2 Pa, charging carbon-containing gas phase molecules with gas purity larger than a preset threshold within a preset range as a source gas, fixing the pre-processed medium window on an anode surface, adopting an anode layer ion beam technology, growing a film on the waveform periodic surface of the medium window by applying direct-current voltage or feeding back microwaves; performing high-pressure deionized water pistol cleaning and deionized water ultrasonic cleaning with preset time length on the medium window with the film grown on surface to remove an amorphous-state carbon element component of the film.

Description

technical field [0001] The invention relates to the technical field of high-power microwaves, in particular to a high-power microwave output window whose surface is periodically carved with a diamond-like film and a manufacturing method thereof. Background technique [0002] High Power Microwave (HPM) refers to electromagnetic radiation with a peak power exceeding 100 MW and a frequency in the range of 1 GHz to 300 GHz. HPM has very broad application prospects in scientific research, civil and national defense fields. With the improvement of peak power and pulse width of high-power microwave devices, especially the development of high-power and miniaturized microwave devices, the breakdown of the dielectric surface in vacuum (referred to as the vacuum-side dielectric window surface) has become a limitation for high-power microwave transmission. The main bottleneck related to the power increase of the transmission system. [0003] The GW-level HPM system is mainly composed ...
