Embodiment Construction

[0029] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] This embodiment provides a C-band ultra-broadband energy selection surface. The working frequency band can cover the C-band, and the spatial field strength can adaptively change its own working state. While not affecting normal working signals, it can adaptively shield strong electromagnetic pulses and protect Electronic equipment safety. refer to Figure 1 to Figure 4 , including a first metal periodic structure 1 , a first dielectric substrate 2 , a second metal periodic structure 3 , a second dielectric substrate 4 and a third metal periodic structure 5 stacked sequentially from bottom to botto...

Abstract

In order to protect the electronic system from the threat of strong electromagnetic pulses, the present invention proposes a C-band ultra-broadband energy selective surface for strong electromagnetic protection, including a first metal periodic structure, a first dielectric substrate, a second The metal periodic structure, the second dielectric substrate and the third metal periodic structure. Wherein the first metal periodic structure on the front side and the third metal periodic structure on the back side are loaded with PIN diodes. By using the multi-layer metal periodic structure and the PIN diode, the frequency selection characteristic of the incident electromagnetic wave and the energy selection characteristic of sensing the electromagnetic energy are realized. The invention can protect the protected electromagnetic wave with arbitrary polarization.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic protection, and in particular relates to an ultra-broadband energy selection surface working in the C-band. 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 facing more complex strong electroma...
