Abstract
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...
