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.

Research

We pursue 4 research programs towards advanced designer materials and devices ...

    Metacrystal

    ... based on novel engineering approaches. Design of next-generation reconfigurable intelligent surfaces using machine learning techniques.

    Tellegen metamaterial

    ... based on novel topologies. Enhancement of weak exotic effects in complex matter in connection to some concepts of quantum field theory.

    Photonic time crystals with metasurfaces

    ... based on novel dimensions. Design of time-varying systems.

    based on novel material substances

    ... based on novel material substances. Exploring new solutions in optoelectronics with topological materials.

    Our current research topics include

    •    Metamaterials and metasurfaces
    •    Spatial and temporal photonic crystals
    •    Magnetics at nanoscale
    •    Axion and Weyl electrodynamics
    •    Electromagnetic nonreciprocity
    •    Fourier optics
    •    Machine learning and inverse design
    •    Reconfigurable intelligent surfaces
