Embodiment Construction

[0031] Such as Figure 2 to Figure 4 As shown, it is a broadband low-dispersion metamaterial according to the first embodiment of the present invention, which includes a first substrate 1, a plurality of artificial microstructures 3 attached to one side surface of the first substrate 1, and a plurality of artificial microstructures 3 covered on the second substrate 2. The artificial microstructure 3 has a first main line 31 and a second main line 32 perpendicularly bisecting each other, the first main line 31 and the second main line 32 have the same length, and both ends of the first main line 31 extend toward the second main line 32 Two first branch lines Z1 are formed, and two ends of the second main line 32 extend toward the first main line 31 to form two second branch lines Z2.

[0032] figure 2 It is a perspective view, that is, it is assumed that the first substrate and the second substrate are transparent, and the artificial microstructure is opaque.

Abstract

The invention relates to a wideband low-dispersion metamaterial. The wideband low-dispersion metamaterial comprises a first base plate and a plurality of artificial microstructures attached onto one side surface of the first base plate, wherein the artificial microstructure is a silk yarn made from a conductive material and comprises a first main line and a second main line which are crossed; the two ends of the first main line extend to the second main line so as to form two first branch lines; and the two ends of the second main line extend to the first main line so as to form two second branch lines. According to the wideband low-dispersion metamaterial, more stable refractive index can be provided in a wider frequency range, namely the characteristics of wide band and low dispersion are achieved.

Description

technical field [0001] The invention relates to the field of metamaterials, more specifically, to a broadband low dispersion metamaterial. Background technique [0002] The characteristic that the refractive index of a material changes with frequency is dispersion. Currently, commonly used metamaterials usually adopt such as figure 1 The split resonant ring structure (SRR) shown. Figure 6 It is a simulation of it (refractive index parameters). It can be seen that the refractive index is relatively stable (low dispersion) for incident electromagnetic waves in the range of 0-5GHZ. However, in some fields (such as microwave antennas), it is necessary to Low dispersion characteristics are realized in a wider frequency band, that is, the smooth change of the refractive index in a wider frequency band. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a broadband low-dispersion metamaterial that can achieve low disper...
