Abstract
An electromagnetic absorption metamaterial having an upper surface in a working environment, comprising a periodic resonant unit array. The metamaterial is provided with a dielectric composite film on the upper surface and the film is obtained by laminating solid dielectric layers in different thickness proportions. Materials of said dielectric composite film are selected from at least two materials of silicon oxide, silicon nitride, aluminum oxide, magnesium fluoride and silicon. By selecting different types of dielectric films and laminating the dielectric films in certain proportions, the metamaterial of the present application can obtain a dielectric film having a refractive index between the maximum and minimum refractive index in selected media, thereby achieving more flexible and controllable modulation of surface lattice resonance. The dielectric composite film is obtained by laminating solid dielectric layers in different thickness proportions, and therefore can work in almost any working environment, even in liquid or moving environments.
