The International Institute of Zakharenko Waves (IIZWs) investigates complex systems such as layered and quantum systems. Indeed, any complex system, where dispersive waves (for example, dispersive Rayleigh and Bleustein-Gulyaev type waves as well as Love and Lamb type waves) can propagate, is of a great interest for the Institute. The Institute will study different dispersive and nondispersive waves both theoretically and experimentally, including different applications of the waves for signal processing (filters, sensors, etc.) and the so-called structural health monitoring.
The hot project by the IIZWs entitled "The development of instatnt interplanetary communication" is the most important for our civilization because the successful realization of this project will allow us to communicate without any delay with neighbour planets, star systems, and even galaxis. It is necessary here to mention that the time delay for communication with the planet Mars is from 8 to 20 minutes that is actually huge delay.
Several additional M.Sc. projects and Ph.D. projects (theoretical and possibly, experimental) are available below:
