Special Issue Information
Dear Colleagues,
Vibration is one of the most ubiquitous energy sources in the ambient environment. Suppressing vibration is of great importance in numerous engineering applications. Due to the low-frequency band gap phenomenon, utilizing metamaterials for vibration suppression has attracted lots of research interests in the past two decades. On the other hand, another group of researchers is dedicated to harnessing and converting ambient vibration energy into electrical energy to power low-power consumption micro-electro-mechanical systems (MEMS). As metamaterials can be engineered with structural symmetry or asymmetry for wave manipulation, the extraordinary phenomena in metamaterials, such as negative refraction induced wave focusing, the defect state mode, and the topological interface mode, have great potentials to be employed for improving energy harvesting efficiency. Moreover, integrating energy harvesters into metamaterials naturally yields multifunctional systems that have both vibration suppression and energy harvesting abilities. For the above two reasons, some researchers attempted to develop metamaterial-based energy harvesters in recent years. Besides, metamaterials designed with parity-time (PT) symmetry or broken time-reversal symmetry have some unique properties, such as unidirectional wave propagation, that can not be observed in natural materials. Therefore, in recent years, enormous efforts have been devoted to designing and investigating these types of metamaterials with various symmetric or asymmetric features. The aim of this Special Issue is to collect the latest advances in energy harvesting technology, metamaterial research, and the collision between the two directions. It is envisioned that this Special Issue can provide a forum for our colleagues to share their achievements and inspire others to promote their future research.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Symmetry is an international peer-reviewed open access monthly journal published by MDPI.
