Metamaterials are man-made materials with well-designed microstructural geometry. They exhibit various extraordinary physical and mechanical properties that rarely exist in nature. Metasurfaces, also known as low-dimensional metamaterials, have recently been applied to manipulate wave fields by abruptly shifting the phase and amplitude. In the last few years, the potential of these materials has been further facilitated by incorporating stimuli-responsive material that leads to intelligent mechanical metamaterials and metasurfaces; structural and mechanical characteristics are manipulated for various stimuli such as magnetic field, temperature, chemicals, light, electric current, just to name a few. As a consequence, these novel materials promise excellent properties beyond traditional materials.
The emergence of additive fabrication techniques such as 3D printing has boosted the development of smart mechanical metamaterials and metasurfaces, since it is a technique that allows building materials of all sizes, as well as complex geometries with enormous precision. This ability to design smart mechanical metamaterials and metasurfaces with properties originated from its micro-architecture, can find applications in a variety of fields and industries like sensor identification, vibration control, energy harvesting, soft robots, etc. In recent years we have witnessed tremendous advances in designing metamaterials and metasurfaces using topology optimization methods and machine learning/data-driven paradigms. However, how to rationally design smart metamaterials and metasurfaces remains a challenging and significant topic.
The main objective of this special issue is to provide recent advances in theoretical, computational, and experimental research in all topics related to mechanics of smart metamaterials and metasurfaces, and their applications in a broad spectrum of mechanical structures. Topics addressed in this research topic may include, but are not limited to:
• Metamaterials/metasurfaces;
• Smart metamaterials/metasurfaces;
• Active metamaterials/metasurfaces;
• Reconfigurable and Tunable metamaterials/metasurfaces;
• Multifunctional metamaterials/metasurfaces;
• Programmable metamaterials/metasurfaces;
• Piezoelectric metamaterials/metasurfaces;
• Chiral metamaterials;
• Topological protected metamaterials;
• Topology optimization of metamaterials/metasurfaces;
• Artificial intelligence-enabled metamaterials/metasurfaces;
• Engineering applications of metamaterials/metasurfaces.
