Abstract

The invention belongs to the field of space strong electromagnetic field protection, and particularly relates to a broadband high-power microwave adaptive protection device. In order to solve the problems that an existing protection device is low in working frequency band and narrow in bandwidth, the device comprises a switch type metasurface, two layers of band-pass frequency selection surfaces and three layers of dielectric plates. The switch type metasurface is printed on the upper surface of the upper-layer dielectric plate; the two layers of band-pass frequency selection surfaces are printed on the upper surfaces of the middle-layer dielectric plate and the lower-layer dielectric plate, and the two layers of band-pass frequency selection surfaces are the same in structure. An air layer is arranged among the three layers of dielectric plates; each unit of the switch type metasurface is composed of two square metal rings, and the metal ring on the outer side is connected with the adjacent unit to form a grid structure. Four gaps are etched at the midpoints of four edges of the inner-layer square ring, and PIN diodes are bridged on the four gaps; each unit structure of the band-pass frequency selection surface is formed by etching four rhombic gaps on a metal sheet.

Description

technical field [0001] The invention belongs to the field of strong electromagnetic field protection in space, and in particular relates to a broadband high-power microwave self-adaptive protection device. Background technique [0002] With the continuous development of high power microwave weapon (HPMW) technology, countries all over the world are actively responding to the potential threats generated by HPMW. High Power Microwaves (HPM) are capable of interfering with or destroying electronic devices by radiating large amounts of electromagnetic energy in the microwave spectrum. When the high-energy microwave signal acts on the electronic equipment, if the frequency of the high-energy wave is the same as the operating frequency of the electronic equipment, it will enter the system through coupling and change into a large current, which will cause the components to overheat or even break down. In addition, the receiving and amplifying modules of the system may further ampl...
