Perfect Absorber Based on Mie Dielectric Metamaterials

摘要：

　　An isotropic Mie resonance-based metamaterial perfect absorber with near unity absorbance is experimentally and numerically demonstrated.The metamaterial is constructed with an array of dielectric cubes and a metallic ground plane.A good agreement between experimental and simulated result at X band absorption is achieved, the absorptivities are 97% and 98% at 9.96 GHz, separately The absorption peak of the metamaterial perfect absorber is dependent on the permittivity, the size and the array pattern of the dielectric particles.The Mie resonance of dielectric particles provides a novel mechanism for creating the electric and magnetic resonances and offers a simpler route for the isotropic metamaterial perfect absorber with near unity absorbance.
