Metamaterials are artificial structures which are engineered to achieve new and unusual physical properties, including negative refraction, invisible cloaking, ultralow thermal conductivity and negative mass density, among many others. Thanks to these thermal, optical and mechanical properties not typically found in nature, they are promising building blocks for developing novel devices and systems that can break the limit of energy transport, conversion, and storage in natural materials. For example, wavelength-selective thermal emitters based on judiciously designed metamaterials can significantly overperform blackbody or other conventional thermal emitters for the application of solar thermophotovoltaics, leading to a high conversion efficiency that may exceed the Shockley-Queisser limit.
Currently, many researchers are developing metamaterial-based devices for energy applications, giving rise to a very active interdisciplinary research field, covering both fundamental theories and practical implementations. These efforts have significantly broadened the understanding of the interaction of electrons, photons, phonons, and other microscopic energy carriers with metamaterials, and provided new strategies for achieving exotic physical properties that can push the limit of energy utilization and render new breakthroughs. Meanwhile, many studies have been conducted focusing on the design and fabrication of metamaterials and devices, aiming to develop a practical route for high-accuracy and scalable manufacturing. Advanced characterization methods have also been developed to experimentally access the exotic physical properties of metamaterial devices in an ultrafast and high spatial resolution fashion. In addition, the integration of metamaterial devices with practical energy systems in real world is of particular interest and importance.
Despite the rapid development in this field, there are still critical challenges to be addressed. First, simultaneously manipulating the transport of different energy carriers in a synergetic way using simple nanostructured metamaterials still remains a challenge, which is vital for many applications like thermoelectrics and multicalorics. In addition, high-throughput and low-cost manufacturing methods for metamaterial devices are in an urgent need for achieving large-scale and high-power energy applications. Moreover, it is quite necessary to develop in-situ experimental characterization techniques with nanoscale resolution for thermal, optical, electronic, and other physical properties of metamaterial devices at work, which are expected to significantly accelerate the R&D process. Furthermore, practical considerations for metamaterial devices in real systems, like durability, stability and compatibility, should be more intensively investigated.
In order to address these challenges, this special issue aims to provide a platform for researchers in this field to share and exchange their outstanding research outcomes so that valuable insights can be obtained for pushing the limit of energy utilization using metamaterials and promoting practical applications. Authors are invited to submit their papers to present their innovative perspectives, insightful theoretical analysis and designs, original experimental investigations, and comprehensive reviews for realizing high-performance metamaterial devices for energy applications.
