Abstract
A simple pattern of a triple band terahertz (THz) absorber is presented. This absorber formed by only triple symmetrical split rings backed with a solid ground layer which is separated by a dielectric layer substrate. It is investigated that the presented absorber has three different absorption bands in which the average of the peaks is close to 96%. Results reveal that the absorption bandwidth of the presented design is insensitive to wave incident angle. In addition, in order to enhance the absorption peaks, a new method is introduced which is based on the difference of split rings thickness. Owing to the simple structure of the proposed absorber, the fabrication process can be quite easy. Therefore, the proposed THz absorber is able to perform in applications such as sensing, detection, and imaging.
