Abstract

The invention relates to a broadband low-dispersion metamaterial which comprises a first substrate and a plurality of artificial microstructures adhered to one side surface of the first substrate; the artificial microstructures are silk yarns made of a conductive material; each artificial microstructure is provided with a first principal line and a second principal line which intersect with each other; two first branch lines are connected to two ends of each first principal line; two second branch lines are connected to two ends of each second principal line; the two ends of each first branch line are bent inwards and extended to form two first broken lines; and the two ends of each second branch line are bent inwards and extended to form two second broken lines. According to the broadband low-dispersion metamaterial provided by the invention, a more stable refraction index can be provided in a broader frequency band, so that the characteristic of broadband low dispersion can be 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. Image 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 dispers...
