Title: | Bidirectional elastic diode with frequency-preserved nonreciprocity | Authors: | Fang, X Wen, J Cheng, L Li, B |
Issue Date: | May-2021 | Source: | Physical review applied, May 2021, v. 15, no. 5, 054022, p. 054022-1 - 054022-11 | Abstract: | The study of nonreciprocal wave propagation is of great interest for both fundamental research and engineering applications. Here we demonstrate theoretically and experimentally a bidirectional, nonreciprocal, and high-quality diode that can rectify elastic waves in both forward and backward directions in an elastic metamaterial designed to exhibit enhanced nonlinearity of resonances. This diode can preserve or vary frequency, rectify low-frequency long wave with small system size, offer high-quality insulation, can be modulated by amplitude, and break reciprocity of both the total energy and fundamental wave. We report three mechanisms to break reciprocity: the amplitude-dependent band gap combining interface reflection, chaotic response combining linear band gap, amplitude-dependent attenuation rate in damping diode. The bidirectional diode paves ways for mutually controlling information and energy transport between two sources, which can be used as wave insulators. | Publisher: | American Physical Society | Journal: | Physical review applied | EISSN: | 2331-7019 | DOI: | 10.1103/PhysRevApplied.15.054022 | Rights: | © 2021 American Physical Society The following publication Fang, X., Wen, J., Cheng, L., & Li, B.
