Abstract

In order to protect the electronic system from the threat of strong electromagnetic pulses, the present invention proposes an X-band energy selective surface, including a dielectric substrate, and a periodically arranged surface structure is printed on the upper surface of the dielectric substrate, and the surface structure includes A series of metal square ring units distributed in an array, the metal square ring unit includes a square metal outer ring, and an I-shaped metal strip group is arranged inside the square metal outer ring; the I-shaped metal strip group includes two T-shaped metal sheets The T-shaped metal sheet is composed of a horizontal metal sheet and a vertical metal sheet connected in the middle of the horizontal metal sheet. The vertical metal sheets of the two T-shaped metal sheets are oppositely arranged and separated by a certain distance, and a PIN diode is loaded between the vertical metal sheets. The invention realizes the X-band energy selective protection characteristics for the first time, and the key indicators such as insertion loss, protection effect, processing complexity and the like are equivalent to the disclosed low-frequency energy selective surface.

Description

technical field [0001] The invention is an energy selective surface working in the X wave band, which is applied to the self-adaptive strong electromagnetic protection of the "front door" of the electronic information system. Background technique [0002] With the rapid development of electronic information technology, the degree of integration, intelligence and miniaturization of various electronic information equipment is continuously improved, its frequency is increasing day by day, energy consumption is also decreasing day by day, and its performance has been greatly improved. The sensitivity and vulnerability of electronic information equipment to strong electromagnetic interference and strong electromagnetic attack. At the same time, in addition to the strong electromagnetic interference that exists in nature, man-made strong electromagnetic interference and attack methods are becoming more and more mature. Sensitive equipment in the military and civil fields are facin...
