All-dielectric structure development for electromagnetic wave shielding using a systematic design approach

摘要: Common dielectric metamaterials for electromagnetic (EM) interference shielding, stealth applications, and EM cloaking generally require larger thicknesses than the wavelength of incidence light. We propose an all-dielectric metamaterial inspired structure using a systematic approach based on phase field design method. The is composed periodically arranged unit structures that have 2D configuration, which sub-wavelength thick over its entire structure. proposed provides anomalous reflections to prevent back toward wave source anti-penetrative microwave band with no conductive materials. digitally fabricated designed 3D printing verified specifications by experiments.
