Abstract:
By designing the ordered structure on the key physical dimensions, metamaterial can obtain extraordinary physical properties. The method gives transparent conductive absorbing metamaterial with broadband and high absorptivity. In this paper, a kind of absorbing metamaterial with indium tin oxide (ITO) glass substrate is designed. The design method of double-sided etched an open loop and linear metamaterial periodic structures is adopted. The thickness of the absorbing metamaterial is 2.5 mm. The research shows that the working bandwidth is between 8.9 GHz and 17.4 GHz, the absorption rate is 90%, and the transmittance of visible light is 85% on average. The absorbing metamaterial has wide application value to solve the problem of visualization and absorption characteristics.
