The concept of metamaterials has drastically altered our way of thinking about light-matter interactions and greatly enriched the field of optics. It has become apparent over the last decade that the light propagation can be manipulated at will using artificially fabricated structures with prescribed optical properties, the diversity of which is limited only by the imagination of the researchers and sophistication of the fabrication techniques. This new understanding has revolutionized the design paradigm of photonic devices and quickly resulted in experimental demonstration of several counterintuitive effects with far-reaching breakthrough applications. Today, scientists and engineers all over the world are combating the fundamental and technological challenges that deter the practical use of the exciting functionalities offered by metamaterials.

We invite authors to submit original research and review articles on modern trends in metamaterial applications. Of particular interest are articles devoted to the novel metamaterial-based devices that are likely to be of utility to people in the short term through their advanced applications in subwavelength imaging, optical sensing, cloaking, photonic integrated circuits, and solar-cell technology. Potential topics include, but are not limited to:

• All-optical and electrooptical dynamic control of light with metamaterials
• Metamaterials in solar-cell technology
• Metamaterials in sensors
• Transformation optics and cloaking
• Metactronics and nanophotonics
• Light harvesting and optical nanoantennae
• Superresolution imaging
• Recent progress in fabrication of 3D, bulk, and large-scale metamaterials
• Novel material platforms for metamaterial applications

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/aoe/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/ according to the following timetable:
