Abstract

Practical realization of multi-band resonant piezoelectric metasurfaces remains challenging, conventionally requiring graded subunits, multi-branch circuitry, digital switching, or active control. As system dimensionality increases, these solutions may become prohibitively complex and expensive, limiting large-scale feasibility. To address this, we investigate a temporally modulated LC-resonator synthesized from self-contained analog circuit. By embedding time-varying resistors into synthetic impedances, continuous harmonic inductances with dynamic reconfigurability are realized. Integrated into local resonators, the proposed circuits open temporal modulation induced sidebands with corresponding wave attenuation zones. Validated through modeling and experimentation, the resulting metasurface is highly scalable and reconfigurable, offering a solution for multi-band vibration control.

通过可重构和可扩展的设计利用超表面的时间调制的多波段波前衰减

实际实现多波段谐振压电超表面仍然具有挑战性，传统上需要梯度亚单元，多分支电路，数字开关或主动控制。随着系统维度的增加，这些解决方案可能变得过于复杂和昂贵，从而限制了大规模的可行性。为了解决这个问题，我们研究了一个由自含模拟电路合成的时间调制lc谐振器。通过在合成阻抗中嵌入时变电阻，实现了具有动态可重构性的连续谐波电感。集成到局部谐振器中，所提出的电路打开了具有相应波衰减带的时间调制诱导边带。通过建模和实验验证，所得到的超表面具有高度可扩展性和可重构性，为多波段振动控制提供了解决方案。

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
