Abstract

In this paper, we design a near-infrared 3D multifunctional metamaterial (3MM) to achieve several different functions based on modified direct binary search (DBS) algorithm. In order to demonstrate the versatility of 3MM, an optical absorber is obtained based on the inverse design technology. Besides, we also utilize it to achieve plasmon induced transparency (PIT) like effect. Finally, to prove the advantages of 3MM, we have designed the corresponding 2D metamaterial to realize the same functions based on the DBS algorithm for comparison. The comparison results show that the performance of 3MM is much better than the 2D metamaterial. Compared with previous works, our proposed 3MM not only demonstrates the advantages of 3D metamaterials in manipulating the absorption spectrums and PIT-like effects but also provides a general framework for other spectrum-related functions in various field, such as imaging, sensor, chemical analysis and so on.
