Embodiment Construction

[0026] The present invention will be further described below with reference to the drawings and embodiments.

[0027] Such as figure 1 Shown is the structure diagram of the present invention. An ultra-wideband energy selection surface, comprising a dielectric substrate, a first metal structure printed on the upper surface of the dielectric substrate, and a second metal structure printed on the lower surface of the dielectric substrate;

[0028] The first metal structure is two sets of the same rail-type combined shape; the rail-shaped combined shape includes two mutually parallel horizontal metal bars and a plurality of mutually parallel vertical metal bars connecting the two horizontal metal bars. The longitudinal metal bars are arranged at equal intervals, and each longitudinal metal bar is loaded with several diodes;

[0029] The second metal structure is a grid composed of metal bars.

[0030] In an embodiment, in the first metal structure, two sets of horizontal metal strips wit...

Abstract

The invention belongs to the technical field of the material, and specifically relates to an ultra wide band energy selection surface. The ultra wide band energy selection surface comprises a medium substrate, a first metal structure printed on an upper surface of the medium substrate, and a second metal structure printed on a lower surface of the medium substrate; the first metal structure is twogroups of same rail-mounted combination shapes; each rail-mounted combination shape comprises two mutually parallel cross metal strips and a plurality of mutually parallel longitudinal metal trips for connecting two cross metal strips; the longitudinal metal strips are arranged at intervals, and a plurality of diodes is loaded on each longitudinal metal strip; the second metal structure is a gridcomposed of the metal strips. The ultra wide band energy selection surface disclosed by the invention has the advantages that the multilayer metal periodic structure and the PIN diodes are used for realizing the frequency selection feature on incident electromagnetic wave and the energy selection feature for sending the electromagnetic energy, and the ultra wide band energy selection surface is anovel and self-adaptive front-door electromagnetic signal suppression technology.

Description

Technical field [0001] The invention belongs to the technical field of materials, and specifically relates to an ultra-wideband energy selection surface. Background technique [0002] With the rapid development of electronic information technology, the degree of integration, intelligence, and miniaturization of various electronic information equipment continues to increase, their frequency is increasing, energy consumption is also decreasing, performance has been greatly improved, and at the same time, it has greatly increased Due to the complexity of the electromagnetic environment and the sensitivity and vulnerability of electronic information equipment to strong electromagnetic interference, the electromagnetic compatibility design of the system is facing unprecedented challenges. [0003] At present, the traditional electromagnetic compatibility design and strong electromagnetic pulse suppression methods are mostly based on "backdoor" suppression methods such as filtering, shie...
