ARTIFICIAL ELECTROMAGNETIC MATERIAL

摘要

Provided in the present invention is an artificial electromagnetic material comprising at least one material lamella. Each material lamella comprises a substrate and artificial microstructures attached to the substrate. Each substrate is virtually partitioned into multiple substrate units arranged in an array. Each substrate unit has attached thereto a pair of artificial microstructures. The pair of artificial microstructures comprises a first artificial microstructure and a second artificial microstructure of different shapes. A dielectric constant of the artificial electromagnetic material of the present invention increases gradually from zero in a certain frequency band, thus the material is provided with reduced dielectric constant in the certain frequency band, thereby meeting the requirements of specific scenarios.
