摘要：

We report a broadband absorber in the infrared regime by using uniform-sized hyperbolic metamaterial composed of metal-dielectric pairs with different filling ratios. We found that the broadband absorption originated from the multiple slow-wave modes. Furthermore, the absorption bandwidth can be engineered by adding or reducing metal-dielectric pairs. In addition, the absorption performance of the proposed absorber retains well in wide angles. This broadband absorber is a good candidate for potential applications such as detection and phase imaging.
