Mie-Metamaterials-Based Electromagnetic Absorbing Concrete

Abstract

A metamaterial structure using steel reinforcement and dielectric cubes was designed, which was introduced into concrete to improve the electromagnetic wave absorption performance of concrete. A near-unit absorption peak at 9.82 GHz was generated in simulation and experimental results. It is also demonstrated that this metamaterial absorbing concrete is insensitive to polarization and can operate at wide angle of incidence.
