A reconfigurable device with magnetron function based on plasma/dielectric multilayer structure

Abstract

The invention discloses a magnetic-control function reconfigurable device based on a plasma / dielectric multilayer structure. The plasma / dielectric multilayer structure comprises dielectric layers andplasma layers, wherein each plasma layer comprises an electrode array for excitation, an electrically-controlled magnet on the back (an electrically-controlled magnetic pole) and an inert gas inside the plasma layer; the magnetized plasma obtained through programming control and the dielectric layers form the multi-layer structure, and forms the plasma / dielectric multilayer structure through iteration by taking a fractal series as a rule. According to the magnetic-control function reconfigurable device, the function reconfigurability of the device can be realized by controlling the magnitude of the magnetic field intensity of the electromagnets by means of programmable control array, the integration of an omnidirectional reflector, a polarization separator and an isolator can be realized,function switching of the device and tuning of the operating frequency and bandwidth are realized through changing voltages at both ends of a plasma excitation source, and the magnetic-control function reconfigurable device has the advantages of compact structure, easy implementation of chip integrated design, wider operating bandwidth and the like.

Description

technical field [0001] The invention relates to the fields of electronic communication, microwave device technology and plasma practical technology, in particular to a reconfigurable device with magnetic control function based on a plasma / medium multilayer structure and a realization method. Background technique [0002] With the development of information technology, the importance of radio frequency systems in communication systems is becoming more and more apparent. Functional devices with single functions in the past, such as waveguides, reflectors, filters and mode separators, have been difficult to meet people's requirements for communication systems. With the discovery of new materials and new processes, people have increasingly "strict" requirements for functional devices in communication systems, such as miniaturization, multi-function, tunability and easy integration. With the mastery of modern people's integration technology, the integrated design of functional d...

AI Technical Summary

Problems solved by technology

The biggest disadvantage of the modification method is that when each functional device is switched, additional control circuits and modules have to be introduced, which not only increases the cost of the device but also brings unavoidable electromagnetic compatibility problems

The problems faced by the existing technology also include that it is difficult to achieve tunability in the working frequency. If the tunable working frequency is to be realized, lumped components have to be added, such as: transformer diodes, transistors and variable capacitors, etc.

These devices have to add additional feed circuits, and it is difficult to make the entire device miniaturized and flexibly adjust the frequency dynamically

There is also a fatal shortcoming in the prior art: the working bandwidth is narrow
