Title: | Novel negative mass density resonant metamaterial unit cell | Authors: | Čeljuska Norbert Sečujski Milan Crnojević-Bengin Vesna |
Issue Date: | 2015 | Journal: | Physics Letters, Section A: General, Atomic and Solid State Physics | Abstract: | © 2014 Elsevier B.V. In this paper a novel resonant unit cell of one-dimensional acoustic metamaterials is presented, which exhibits negative effective mass density. We theoretically analyze the unit cell and develop a closed analytical formula for its effective mass density. Then we proceed to demonstrate left-handed propagation of acoustic waves using the proposed unit cell. Finally, we present its dual-band version, capable of operating at two independent frequencies. | URI: | https://open.uns.ac.rs/handle/123456789/18049 | ISSN: | 0375-9601 | DOI: | 10.1016/j.physleta.2014.10.036 |
