C-Band Broadband Energy Selective Surfaces

Abstract

The invention proposes a C-band broadband energy selective surface, which includes a dielectric substrate and a metal structure layer attached to the surface of the dielectric substrate. The metal structure layer is a periodic array structure formed by uniform arrangement of multiple metal units. The metal unit includes two annular metal patches, the two annular metal patches are longitudinally adjacent and the longitudinally adjacent transverse ring edges are separated by a certain distance, and the longitudinally adjacent transverse ring edges of the two annular metal patches are loaded with lumped capacitance. The two ends of the lumped capacitor are respectively welded on the longitudinally adjacent transverse ring edges of the two annular metal patches. Two vertical metal patches are oppositely arranged between the transverse ring edges of each annular metal patch with a certain distance between the two vertical metal patches, and a switching diode is loaded between the two vertical metal patches. When the external signal energy exceeds the design threshold, the diode automatically transforms into a forward-biased state, the signal passband is closed, and strong electromagnetic pulses are shielded, thereby protecting electronic equipment.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic protection, and in particular relates to a 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 electromagnetic ...

Problems solved by technology

However, it contains a two-layer structure and the number of diodes required for a single unit is as high as 9, which is not only costly, but also low reliability

However, the energy selection device applied to the C-band is still blank.
