Abstract
The present invention provides an artificial electromagnetic material, comprising at least one material sheet layer; wherein each material sheet layer is provided with a first substrate and a second substrate which are oppositely arranged; and a plurality of artificial microstructures are attached on a surface, facing the second substrate, of the first substrate. The first substrate and the second substrate on both sides of the artificial microstructure are in such tight contact therewith that the number of electric field lines passing through the substrates is increased and the equivalent permittivity of the artificial electromagnetic material is effectively improved.
