Designer Materials and Devices

The Designer Materials and Devices group is located at the Department of Electronics and Nanoengineering, Aalto University. Our research interests span multiple dimensions: (i) from fundamental electrodynamics to functional devices; (ii) from microscopic to macroscopic electromagnetic systems; (iii) from microwaves to visible; (iv) from one-dimensional to four-dimensional geometries. The core of our research is in metamaterials and metasurfaces.

Nature has provided us with an abundance of materials hosting diverse physical properties. Among them, electrodynamic material properties stand out as one of the most important for a variety of applications, from communications and electronics to medicine and entertainment. However, the range and strength of electrodynamic properties of natural materials are often limited and cannot satisfy rapidly growing needs of the modern industry. This circumstance has led to the emergence of an important category of designer matter which embraces composites, colloids, photonic crystals, metamaterials, and others. The key aim of this field is to develop new materials with desired properties and to explore and invent principally novel functionalities.
