Designer Materials and Devices

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.
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
• Advanced diffractive optical components.
If you are interested in working with us (M.Sc. & Ph.D. thesis, research visit, collaboration) and/or have your own fellowship/funding, please contact Prof. Viktar Asadchy.
Open positions
We are looking for a talented and driven doctoral student to join our team. We invite exceptional candidates who are passionate about electromagnetism, nanophotonics, and quantum electrodynamics to contact Prof. Viktar Asadchy. The doctoral student will work on the new Academy Project ("Designer Composites with Axionic Properties") and other related projects.
