Abstract

The invention discloses a tunable, high-resolution and multi-band enhanced plasma generating device, and relates to the technical field of low-temperature plasma application. The invention aims to solve the problems that an existing multi-band signal transmission device is low in transmission efficiency and needs to be used in cooperation with a signal amplifier, and a single-layer plasma enhancement device is poor in band-pass frequency characteristic. N plasma covers are coaxially nested, and the N plasma covers are sequentially a first plasma cover, a second plasma cover to an N plasma cover from inside to outside; an antenna system is located in the cover of the first plasma cover; a dipole antenna is used for emitting a plurality of target waveband electromagnetic waves or receiving target waveband electromagnetic waves input by the background electromagnetic field through the N plasma covers; each plasma cover enhances the intensity of the target waveband electromagnetic wave signals emitted by the dipole antenna or extracts and enhances the target waveband electromagnetic wave signals from the background electromagnetic field, and the enhancement range is that the logarithmic gain of the power of the signals emitted by the N plasma covers is greater than or equal to 10dB. The device disclosed by the invention is used for enhancing signals.

Description

Technical field [0001] The invention relates to a plasma device. It belongs to the application technical field of low-temperature plasma. Background technique [0002] With the development of modern microwave communication technology, in order to make full use of cable bandwidth resources, wavelength division multiplexing is usually used to increase transmission capacity. Among them, a wavelength division multiplexer is used at the signal sending end to combine carriers of different wavelengths for transmission, and a demultiplexer (equivalent optical bandpass filter) is used at the signal receiving end to separate each signal. In order to ensure the quality of communication, multiplexers and demultiplexers need to have the characteristics of low in-band insertion loss, obvious separation isolation, and high stability of the center wavelength. In addition, in the context of complex electromagnetic environment operations in modern military warfare, the enemy and ourselves often ...
