- Abstract
- In this article, we propose a low-cost three-dimensional (3D) printed metamaterial absorber. The proposed metamaterial consists of a periodic structure of circular truncated cones. The dielectric materials supporting the circular truncated cone are made from a poly(lactic acid) filament using the 3D printer. The conductor of the circular truncated cone is developed by spraying silver-coated copper. The performance of the proposed absorber is numerically and experimentally investigated. The simulated and measured absorptivity are 91% and 95% at 10.8 and 10.81 GHz, respectively. As a result of the 3D printing and silver spray coating processes, the proposed absorber can be easily fabricated at a low cost.
