Title:
ELECTROMAGNETIC ABSORPTION METAMATERIA
Document Type and Number:
WIPO Patent Application WO/2019/029207
Kind Code:
A1
Abstract:
The present invention provides an electromagnetic absorption metamaterial having an upper surface in a working environment, comprising a periodic resonance unit array. The upper surface of the electromagnetic absorption metamaterial is provided with a dielectric composite film. The film is obtained by laminating solid dielectric layers in different thickness proportions. The material of the dielectric composite film is selected from at least two of silicon oxide, silicon nitride, aluminum oxide, magnesium fluoride, or silicon. According to the electromagnetic absorption metamaterial of the present invention, by selecting different types of dielectric films and laminating the dielectric films in certain proportions, a dielectric film having a refractive index between the maximum refractive index and the minimum refractive index of selected media can be obtained, thereby implementing 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 almost work in any working environment, or even a liquid or moving environment.
